Valve Care and Maintenance

Since the Pressure-Tru® Valve is an automatic valve, it is imperative to make sure that the system is free of rocks and debris. This can be ensured by flushing the system. Upon completion of valve installation and testing, it is important that the system be slowly filled with water to prevent water hammer. It is recommended that a flow test be run periodically to allow the Pressure-Tru® Valve to open and reset itself. If valve repair is required, the system should be drained. Access to internal components can be achieved by removing the bell housing and flange. The body need not be removed from the system. Contact the factory for repair parts.

PRESSURE-TRU® FIRE VALVE OPERATIONHow Sprinkler and Hose Valves OperateThe Wilkins Pressure-Tru® valves reduce high inlet pressure to a lower downstream pressure.

The valves are forced open by high incoming pressure (A) pushing up on the valve plunger (1). The Z2100 and Z3000 series are also biased open by an adjustable spring (2).The valves remain in an open position until lower downstream pressure (B), sensed through the stem orifice (4) on top of the large piston area (3) forcing the plunger down on to the seat, is trying to close the valve while the higher inlet pressure (A) (and the spring in the Z2100 & Z3000 series) is trying to open the valve. For the Z2100 and Z3000 series, the amount of the lower downstream pressure needed to close the valve is proportional to the preloaded spring force. For the ZW4000 series, the amount of the lower downstream pressure needed to close the valve is proportional to the piston size (3). When the valve is pressurized, the lower downstream pressure exerted on the piston holds the valve in the closed position until there is a water demand caused by a discharging fire sprinkler head or hose nozzle. As the discharge occurs, the lower downstream pressure on top of the piston decreases, allowing the higher inlet pressure to open the valve in order to satisfy the water demand. The valve will continue to modulate in the open position until the demand ceases. At that point the lower downstream pressure will increase on top of the piston until the plunger is forced closed again.

In addition to its pressure reducing function, the Pressure-Tru® valve can be held manually in the closed position for shut-off service. When the hand wheel (5) is rotated to the closed position, the hand wheel stem forces the plunger onto the seat, holding the valve shut.

4

Pressure-Tru® sprinkler control valves are available with an integral supervisory switch (Z3004SS) to monitor the open/closed position of the valve, or available with a bracket (MSA) to mount an external supervisory switch.

PRESSURE-TRU® INSTRUCTIONS

Field Setting InstructionsZ2100 & Z3000 Series

1. Pressure gauges should be installed upstream and downstream of the Pressure-Tru® Valve.

2. Refer to flow data charts and letter designation, from #6 above, and to the corresponding listed dimensions to determine the proper "A" DIMENSION setting.

3. Open valve by rotating hand wheel counter-clockwise.

4. Remove wheel handle assembly by loosening the upper coupling nut.

5. Insert a 1-1/16" deep-well socket (for 2-1/2" valve) or a 15/16" deep-well socket (for 1-1/2" valve) into bell housing and on to adjusting nut.

6. Turn the adjusting nut clockwise to increase “A” DIMEN- SION setting and counter-clockwise to reduce “A” DIMEN- SION setting. Increasing the “A” DIMENSION raises the downstream pressure. Decreasing the “A” DIMENSION lowers the downstream pressure. NOTE: Do not exceed 175 PSI static or maximum “A” DIMENSION setting of 9/16" (1-1/2" valve) and 1-3/16" (2 1/2" valve) (see illustration).

7. After installation, the valve shall be tested in accordance with NFPA 14 and tested periodically thereafter in accordance with NFPA 25.

CAUTION: To prevent a false reading during the setting process it is necessary that a test valve be opened and closed downstream to relieve the locked-up pressure in the system.

If the system requires the valve to remain in a static position to main-tain a regulated dead-end service pressure, it is good engineering practice to incorporate a pressUre relIef vAlve within the system. NFPA 13 requires a relief valve on sprinkler systems.

Choosing the Correct Setting - All Pressure-Tru® Valves In choosing the correct setting for each Pressure-Tru® Valve, refer to the Residual Pressure Flow Charts, Static Pressure Charts on the next page, and the following procedure:

1. Determine the demand in gallons per minute required downstream of the valve. 2. Determine the standpipe residual or “flow pressure” at the valve inlet. 3. Locate the appropriate flow chart based on GPM required, valve type, and size. 4. Locate the inlet residual pressure on the vertical axis of the chart and draw a horizontal line from this

pressure across the chart. 5. Locate the desired valve outlet residual pressure on the horizontal axis of the chart and draw a vertical

line from this pressure. 6. The curve nearest the intersection of the two lines drawn is the appropriate setting for the valve and is

identified by the letter designation at the end of the curve line and the corresponding dimension on the bottom of the page.

7. To determine the static outlet pressure, locate the static chart for the appropriate valve size. Deter- mine the valve inlet static pressure shown on the vertical axis and draw a horizontal line from that pressure to the appropriate curve determined above, then draw a vertical line down to the horizontal

axis and read the static outlet pressure.

5

In designing a sprinkler system, a minimum of 20 psi pressure differential (the difference between the inlet static pressure and the valve outlet set static pressure) is recommended to assure a well regulated and effi-cient system.

CHOOSING THE CORRECT SETTINGSIn designing a sprinkler system, a minimum of 20 psi pressure differential (the difference between the inlet static pressure and the valve outlet set static pressure) is recommended to assure a well regulated and efficient system. In choosing the correct setting for the Pressure-Tru® valve, refer to the Residual Pressure Charts, Static Pressure Chart and the following procedures: 1. Determine the demand in gallons per minute required downstream of the valve. 2. Determine the standpipe residual or “flow pressure” at the valve inlet. 3. Locate the appropriate flow chart based on GPM required and body style. 4. Locate the inlet residual pressure on the vertical axis of the chart and draw a horizontal line from this pressure across the chart. 5. Locate the desired valve outlet residual pressure on the horizontal axis of the chart and draw a vertical line from this pressure. 6. The curve nearest the intersection of the two lines drawn is the appropriate type for the valve. 7. To determine the static outlet pressure, locate the static chart. Determine the valve inlet static pressure shown on the vertical axis and draw a horizontal line from that pressure to the appropriate curve determined above, then draw a vertical line down to the horizontal axis and read the static outlet pressure.

MAXIMUM RATED INLET PRESSUREMaximum inlet pressure, to assure a maximum outlet pressure of 175 psi. Inlet side of valves can be safely tested up to 400 PSI during system hydrostatic leak test.

Proper performance is dependent upon licensed, qualified personnel performing regular, periodic testing according to WILKINS’ specifications and prevailing governmental & industry standards and codes and upon following these installation instructions. Failure to do so releases WILKINS of any liability that it might otherwise have with respect to that device. Such failure could also result in an improperly functioning device.
