SYSTEM DESCRIPTION

The Groth Model 220 test stand will perform

three basic low pressure and vacuum relief valve

tests:

1) Pressure Set Test2) Vacuum Set Test3) Pressure Leak Test

It consists of a test flange with an accumulator

and control panel integrally mounted on a

common structure.


9/51

2

The test flange is designed to test valves from 2”

through 24”. Adapters, gaskets and clamps are

provided for mounting these valves.

The control console is located to the side of the

test flange and includes the necessary valves and

gauges to accurately perform the tests.

Air flow, to or from the valves being tested, can

be smoothly varied to provide an accurate

verification of pressure or vacuum setting. The

valve leakage rate can be tested under pressure

condition with the use of three parallel flow

meters isolated by block valves.

A volume pressure vessel inside the table serves

as an accumulator to dampen pressure pulsation.

Pressure or vacuum can be smoothly regulated

to ensure an accurate test of set pressure or valve

leakage.

An electrically driven vacuum pump provides

vacuum to the test flange. It is isolated from

positive test pressure by a flow regulating valve.

The vacuum pump On/OFF switch is located on

the front of the console.

INSTALLATION

Connect plant air and water to the control

console and pipe the drain/vent port to a suitable

location.

Connect the 115 VAC, 1 phase, 60 HZ power

supply to the terminal strip in the control

console. This provides power for the optional Digital Gauge and the vacuum pump.

PROCEDURES

Low pressure or vacuum relief valves should be

tested according to API Standard 2000, or the

applicable standard for the jurisdiction in which

the valve is installed.

The Groth Model 220 Test stand meets the

requirements of API 2000.

OPERATION

This section describes the location and function

of the individual components of the test stand.

Please refer to the assembly drawing C-91512

and the piping schematic A-91641.

1) The control panel is a heavy gage, weather-

proof enclosure with hinged back door.

2) This gage continuously displays pressure or

vacuum at the test flange. There is no

isolation valve, but a pressure limiting valve,

set at 20 PSIG, prevents damage to the gage.

3) A manometer is used for low pressure or

vacuum measurement. The fluid supplied

has a specific gravity of 1.00. As a

substitute, water may be used, with orwithout an appropriate dye.

4) Three flowmeters are used to accurately

measure flow to the test stand throughout

the range of 0 to 100 SCFH. Each

flowmeters includes a SS needle valve for

precise flow control. The flow that is

necessary to maintain constant pressure is

the leakage rate of the valve at that pressure.

Note: To determine leakage, all test stand piping

connections must be bubble tight.

5) The switch is used to start and stop the

vacuum pump for vacuum testing. The

pump may be running for the duration of the

test even when flow is shut off with the test

valve.

6) Block valves [2] are used to isolate the

pressure and vacuum manometer ports. Only

one valve should be open at any time and

both must be closed if pressure or vacuum

exceeds 24” WC.

Note: Exceeding the range of the manometer

may cause damage or loss of fluid.

7) The vacuum pump is located inside the

stand and provides vacuum to the test

flange. Pump On/Off function and flow are

regulated from the control panel. See the

attached manufacture’s manual for

maintenance and operation of the pump.

8) This gage displays the pressure of the

compressed air supplied to the test stand.

9) This optional digital gage continuously

displays pressure at the test flange. It willnot display vacuum. It can be set to retain

the maximum pressure attained during a test.

A pressure limiting valve also protests this

gage. See the attached manufacturer’s

manual for operation and calibration of this

gage.

“Vacuum Pump” Vacuum pump switch

“Vent” Vents tank to atmosphere

“Pressure Test” Pressure test flow

“Vacuum Test” Vacuum test flow

regulating valve

11) Test valves [one each for pressure and

vacuum] are used to slowly flow air into or

out of the accumulator. These regulating

needle valves provide precision control of

test pressure.

The vent valve exhausts the accumulator to

the atmosphere, or allows atmospheric

pressure to replace vacuum in the

accumulator. The vent valve must always be

open when mounting or removing a valve

from the test flange.

12) The test flange is used for mounting all

valves from 2” through 24” for testing.

Valves from 2” through 12” are mounted on

an appropriate spacer with a soft rubber

gasket on either side, and secured with “U”

clamps. Heel blocks are provided for the

clamps.

Typical Pressure/Vacuum valve mounting

Valves from 16” through 24” are mounted

directly to the test flange on an appropriate

soft rubber gasket. They are secured with

swing clamps or bolted directly to the

flange.

Typical Emergency valve mounting

13) The test stand is heavy steel construction

with an aluminum control mounting panel.

14) The accumulator vessel is located under the

test flange and provides sufficient air

volume to provide smoothly regulated

pressure or vacuum to the flange.

Warning:

Always vent the accumulator completely

before releasing the clamps on the test

flange..

MAIN TABLE OPERATING INSTRUCTIONS

CLAMPING A FLANGED VALVE ON THE HYDRAULIC TABLE

1. Clean the O-Ring Seal Plate and flange of the valve to be tested of dirt, debris, scale or other matter.

2. If the valve to be tested is 1-1/2” or smaller, place the Adapter Plate centered on the O-Ring Seal Plate

with its O-Rings up. Place the valve to be tested centered on the Adapter Plate. Proceed to Step # 4.

3. Place the flanged relief valve to be tested in the CENTER of the O-Ring Seal Plate. (Install the valvewith the outlet pointed away from the operator or other personnel.)

DO NOT SLIDE THE VALVE ACROSS OR DROP THE VALVE ON THE O-RINGS AS

DAMAGE TO THE O-RINGS MAY OCCUR, GREATLY REDUCING THEIR LIFE.

4. Place the Clamp Arms on top of the inlet flange of the valve to be tested with the ends of the ClampArms extended onto the flange at least as far as the center of the bolt hole circle.

TAKE CARE NOT TO DROP OR SLIDE THE CLAMPING ARMS ON THE O-RINGS ASDAMAGE TO THE O-RINGS MAY OCCUR, GREATLY REDUCING THEIR LIFE.

5. Turn the Hydraulic Clamp Pressure Drain switch to the HOLD position.

6. DEPRESS the Rapid Advance Pre-Clamp Button until the Hydraulic Rams are fully extended. This

will clamp the valve to be tested firmly in place.

7. BACK OFF the Hydraulic Clamp Pressure Regulator counter-clockwise until resistance is

encountered.

8. Turn the Hydraulic Pump Valve to the CLAMP position.

9. Find the appropriate hydraulic clamping pressure for the valve being tested by referring to the

Hydraulic Pressure Chart. Bring up the hydraulic pressure by slowly turning the Hydraulic ClampPressure Regulator clockwise until the required pressure is shown on the Hydraulic Clamp Pressure

Gauge. (For valves of 1-1/2” and smaller, use hydraulic pressures set out for 2" valves as shown on the

Hydraulic Pressure Chart.)

10. Turn the Hydraulic Pump Valve to the OFF position.

NOTE 1: The pressures in the hydraulic pressure chart as theoretical minimums, can, and should be exceeded slightly. If, during a test, the hydraulic pressure increases while the hydrostatic

pressure is increased STOP IMMEDIATELY and increase the hydraulic pressure by turning theHydraulic Pump Valve ON and adjusting the Hydraulic Clamp Pressure Regulator clockwise.

EXPLANATION: The tested valve’s internal pressure can create force that approaches or exceeds the

hydraulic system’s capability to maintain a seal. As this event happens, the valve begins to move away

from the sealing O-Rings. This movement is manifested by a slight increase in hydraulic pressure, whichwill be indicated on the Hydraulic Clamp Pressure Gauge. Continuation of this movement will result in

blown out O-Rings and loss of test pressure.


17/51

6

NOTE 2: If several of the same size and pressure valves are to be tested sequentially, theHydraulic Clamp Pressure Regulator need not be readjusted each time; simply skip steps 7 and 9

above.

CLAMPING A THREADED END VALVE ON THE HYDRAULIC TABLE

The Model RV600-AW may include a Threaded Adapter Plate with a 1-1/2" NPT nipple in the center and

a set of reducing couplings to accept the NPT threads of male valves, 1/2" through 2".

1. Place the Threaded Adapter Plate centered on the O-Ring Seal Plate and clamp in place using the same

procedure for clamping a flanged valve to 3500 psi on the Hydraulic Clamp Pressure Gauge.

2. Assemble and install the required nipples and/or bushings to fit the screwed-end valve being tested.

3. Attach the valve to be tested and proceed with the desired test.

4. To remove a valve, follow the removal instructions under REMOVING A VALVE FROM THE

HYDRULIC TABLE.

REMOVING A VALVE FROM THE HYDRAULIC TABLE

1. If another similar valve is to be tested and it is desirable to preserve the charge in the test vessel(s),

CLOSE the Test Table Isolation Valve(s).

2. OPEN the Test Table Drain Valve and ensure that all test pressure is drained from the valve.

3. Turn the Hydraulic Clamp Pressure Drain switch to the RELEASE position until the Hydraulic ClampPressure Gauge pressure drops to 0 psi, and the Hydraulic Rams are retracted, then Turn the Hydraulic

Clamp Pressure Drain switch to the HOLD position.

4. Retract the Clamp Arms.

DO NOT SLIDE THE VALVE ACROSS OR DROP THE VALVE ON THE O-RINGS AS

DAMAGE TO THE O-RINGS MAY OCCUR, GREATLY REDUCING THEIR LIFE.

5. Remove the valve from the O-Ring Seal Plate.

TEST VESSEL SET UP

The test vessel set up procedure is needed in order to configure the tester for water or air tests. The testvessel accumulators must be used for all water tests. When the test vessel(s) are filled with water to the

level of the test table they will hold approximately HALF their air volume each.

SET UP FOR WATER TESTS

For water tests the water test vessel(s) need to be filled to the level of the test table. Make sure that all

pressure is relieved from all test vessels.


18/51

7

1. Vent the table and the test vessel(s) to be filled of all pressure, OPEN the Test Table Isolation Valve,

and remove the valve from the test table.

2. CLOSE the Test Table Drain Valve and OPEN the Test Vessel Vent Valve.

3. OPEN the Supply Water Block Valve and the test vessel(s) will begin to fill until water overflows the

test table, at this point, CLOSE the Supply Water Block Valve and see if the water level remains at the

test table.

EXPLANATION: As water flows into the bottom of the line from the test vessels to the table the

air in the system is evacuated out of the table and the Test Vessel Vent Valve. This air will flow

faster from the large port in the table than it will from the Test Vessel Vent Valve at the top of thetest vessel. This allows the water to appear at the opening of the table before it has reached the

same level in the test vessel.

4. If needed, OPEN the Supply Water Block Valve repeatedly until water remains at the level of the test

table.

5. CLOSE the Test Vessel Vent Valve. At this point, the tester is ready for any of the water tests.

SET UP FOR AIR TESTS

The test vessel set up for air tests consist of OPENING the Test Table Isolation Valve(s). If the tester has

just previously been set up for a water test it is required that the test vessel and line to the table be drained

before an air test may be performed. This is accomplished by the following procedure:

1. Clamp a blind flange in the test table to approximately 1000 psi.

2. Pressurize (or reduce the pressure in) the test vessel(s) to be drained to 100 psi.

3. OPEN the Test Table Isolation Valve.

4. OPEN the Test Table Drain Valve until the water has been drained then CLOSE.

5. Repeat 4 until no more water flows from the Test Table Drain port.

6. OPEN the Test Table Drain Valve and the Test Vessel Vent Valve until the air pressure is lost thenCLOSE both valves.

7. Once the pressure is gone, and the blind flange is removed, the Blow Down Valve may be OPENEDcarefully to “dry” the system.

REGULATED SEAT TIGHTNESS AND LOW VOLUME SET PRESSURE TESTS WITH AIR

This test is carried out without the use of the test vessel.

This procedure begins with all valves CLOSED and NO PRESSURE on the Table.


19/51

8

1. CLOSE Test Table Isolation Valve(s). If the test vessel is charged from a previous test there is no

need to empty this pressure. These tests may be performed no matter what pressure is in the testvessel.

2. Follow the instructions for CLAMPING A FLANGED VALVE ON THE HYDRAULIC TABLE.

3. Connect the appropriate Test Gauge to the Table Gauge Port.

4. BACK OFF the HP Air Regulator and OPEN the HP Air Inlet Valve.

5. OPEN the Table Inlet Valve.

6. Slowly TURN the HP Air Regulator clockwise until the pressure reached the seat tightness test

pressure (usually 90% of Set Pressure).

7. Measure the seat leakage per your procedure or use the available API 527 seat leakage fixtures.

8. At this point, the seat tightness test is complete. If it is desired to lift the valve with the limited flowrate available through the regulator, remove any fixture on the outlet of the valve and continue to

increase the pressure on the inlet of the valve with the HP Air Regulator until the valve lifts.

9. Quickly BACK OFF the HP Air Regulator.

10. To remove the valve:

A. CLOSE the HP Air Inlet Valve.B. Completely BACK OFF the HP Air Regulator.

C. OPEN the Test Table Drain.

D. CLOSE the Table Inlet Valve.E. Follow the instructions in REMOVING A VALVE FROM THE HYDRAULIC TABLE.

HIGH VOLUME AIR SET PRESSURE TESTS

These tests are conducted using the test vessel up to 3,500 psi.

This procedure begins with no pressure in the test vessel, the Test Table Isolation Valve OPEN and

all other valves CLOSED or OFF.

1. Follow the SET UP FOR AIR TEST instructions in the TEST VESSEL SET UP section.


3. Connect the appropriate Test Gauge to the Table Gauge Port.

4. While observing the Test Gauge, OPEN the Blow Down Valve until the valve being tested lifts then

quickly CLOSE.

5. As the valve lifts, note the lift pressure on the Test Gauge.

6. CLOSE the Test Table Isolation Valve(s).


20/51

9

7. OPEN the Test Table Drain Valve.

8. Follow the instructions in REMOVING A VALVE FROM THE HYDRAULIC TABLE.

This procedure begins with pressure in the test vessel, the Test Table Isolation Valve, and all other

valves CLOSED or OFF, and no valve on the test table.


2. Connect the appropriate Test Gauge to the Table Gauge Port and OPEN Table Gauge Port Valve.

3. If the pressure in the test vessel is higher than the anticipated set pressure of the valve to be tested

OPEN the Test Vessel Vent Valve until the pressure is lower than the anticipated set pressure.

4. When the pressure in the test vessel is lower than the anticipated set pressure of the valve being tested

OPEN the Test Table Isolation Valve(s).

NOTE 3: It is possible to equalize the pressure in the test vessel with the pressure on the table

before OPENING the Test Table Isolation Valve. This reduces the wear on the Test TableIsolation Valve and will indicate if the valve to be tested will lift unexpectedly, because its set pressure is lower than anticipated, when the Test Table Isolation Valve is OPENED. This is

accomplished by simultaneously OPENING the Table Inlet and Test vessel Fill valves slowly

until the pressure in the test vessel equalizes with the pressure on the table. After equalization

occurs, CLOSE the Table Inlet and Test vessel Fill valves.

5. While observing the Test Gauge, OPEN the Blow Down Valve until the valve being tested lifts then

quickly CLOSE.

6. As the valve lifts note the lift pressure on the Test Gauge.




REGULATED SEAT TIGHTNESS AND LOW VOLUME SET PRESSURETESTS WITH

WATER

These tests may only be performed with the test vessel using HP air over water, up to 3500 psi.

This procedure begins with no pressure in the test vessel, the Test Table Isolation Valve OPEN and

all other valves in the CLOSE or OFF position.

1. Follow the SET UP FOR WATER TEST instructions in the TEST VESSEL SET UP section.

8. At this point, the seat tightness test is complete. If it is desired to lift the valve with the limited flow

rate available through the regulator, remove any fixture on the outlet of the valve and continue to

increase the pressure on the inlet of the valve with the HP Air Regulator until the valve lifts.

9. Quickly BACK OFF the HP Air Regulator.

10. To remove the valve:

A. CLOSE the HP Air Inlet Valve.B. Completely BACK OFF the HP Air Regulator.C. CLOSE the Test Table Isolation Valve

D. OPEN the Test Table Drain.

E. CLOSE the Test vessel Fill Valve.

F. Follow the instructions in REMOVING A VALVE FROM THE HYDRAULIC TABLE.

This procedure begins with water and pressure in the test vessel, the Test Table Isolation Valve and

all other valves CLOSED or OFF, and no valve on the test table.

1. Clamp the valve to be tested.

2. If the pressure in the test vessel is higher than the anticipated set pressure of the valve to be tested

OPEN the Test Vessel Vent Valve until the pressure is lower than the anticipated set pressure.

3. When the pressure in the test vessel is lower than the anticipated set pressure of the valve being testedOPEN the Test Table Isolation Valve(s).

NOTE 3: It is not possible to equalize the pressure in the test vessel with the pressure on the table before opening the Test Table Isolation Valve. Following the procedure to equalizing the pressure

for air tests would introduce air to the inlet of the valve being tested.

4. As the valve lifts note the lift pressure on the Test Gauge.


6. OPEN the Test Table Drain Valve and return to the CLOSE position as soon as the table pressure goesto zero.


BLOW DOWN TESTS

These tests are conducted using the test vessel up to 3,000 psi.

Blow down tests are conducted exactly like the High Volume Set Pressure Tests except that when the

valve lifts the operator will continue to OPEN the Blow Down valve until the pressure on the inlet of the

valve being tested reaches 110% of the set pressure. At this point, the Blow Down Valve is CLOSEDallowing the disk to settle back on the seat at the reseat pressure.

5. Connect the appropriate Test Gauge to the Top Gauge Port and OPEN Top Gauge Port Valve.

6. OPEN the Bottom Fill, and Top Drain valves.

7. CLOSE the Top Fill and Bottom Drain valves.

8. OPEN the Supply Water Block Valve to fill the test valve with water, as indicated by a steady flow of

water from the top vent port.

9. CLOSE the Top Drain valve.

10. BACK OFF the Test Regulator and OPEN the Test Pump valve.

11. Adjust the Test Regulator until the desired pressure is on the test valve.

12. CLOSE the Bottom Fill, Supply Water Block Valve, and the Test Pump valves.

13. Open the System Drain valve until test pressure is relived from the system gauge, then close the

system drain.

NOTE 3: At this point, no flow of test water should show through the valve, test pressure will show on

the top and bottom test gauges, and the system gauge will show zero. If the valve is holding steady test

pressure on the top and bottom test gauges there ARE no leaks in the shell of the valve. If the test

pressure does show pressure decay there MAY be a leak in the shell of the valve. Other causes of pressure decay include leaks in the test system, and/or temperature effects, and/or air trapped in the body

that is being absorbed into the test water at high pressure. A close inspection of the valve body may

confirm a leak in the shell or deny a leak despite an indication of pressure decay on the test gauges.

14. To remove test pressure, OPEN the Bottom Drain Valve.

test gauges, and the system gauge will show zero.

OPTIONAL POV CIRCUIT

The optional POV test circuit provides a valved outlet that when connected to the pilot port of a relief

valve will apply the same pressure to the pilot port that the inlet of the valve sees. After clamping thevalve and connect the pilot port on the valve to be tested to the pilot port on the top of the hydraulic panel

with a line of appropriate pressure rating (not provided with the tester). OPEN the Aux Pilot Valve and

proceed with the test as normal. At the conclusion of the test, remove pressure form the inlet of the valveas usual and CLOSE the Aux Pilot Valve before removing the line from the valve to the tester.

GROTH Testers, Inc. has designed a portable Water Capture/Muffler system for

use with our Relief Valve Test Systems. This system has a hydraulic lift to

adjust for the height of the RV and includes flange adapters that clamp to the

outlet flange and threaded adapters for threaded outlet valves. The System

includes a SS capture/surge drum and high flow muffler to reduce the sound of

air relief valve tests. A relief valve is included to prevent over pressure of the

drum during test. The drum attaches firmly to the outlet of the valve during the

test and is designed to resist the reactive forces of the relief valve during lift.

When furnished with the Data Acquisition System the camcorder mount and

fiber optic light source for water tests are mounted on the drum so that the

camcorder may view the outlet of the valve through an included sight glass.
