2 .1 HOW TO USE A WOUTER WITZELEUROVALVE BUTTERFLY VALVE

Butterfly valves are applied more and more in pipingsystems instead of traditional valves because of theirgeneral advantages (see 2.3).The Eurovalve range is specially designed for thefollowing process functions: 1. Isolating (100% tight shutoff; zero leakage) and/or 2. Flow control regulation ormodulating duties.

ISOLATING, STOP OR SHUT OFF VALVE (ON/OFF)

The butterfly valve is used in the fully open or in theclosed position. With an isolating valve a part of a pipingsystem can be isolated by closing the valve. It preventsflow or leakage into the downstream conduit. Theadvantage of a Wouter Witzel Eurovalve compared withother butterfly valves for this application is the low flowresistance when the valve is open. The design of slim andstreamlined disc shapes results in low pressure lossesand reduced energy costs for the end user. The saving of

energy costs may be several times the initial price of thevalve. Ask for our Technical Data sheet regarding flowthrough on/off valves and energy costs.

REGULATING VALVE

The butterfly valve is used in a partly open position toregulate the pressure, the capacity, level or temperature of a process. The Eurovalve range finds more and moreapplication as regulating valves due to their good linearflow characteristic. Ask for our Technical Data sheetregarding flow control.

2.3 DESIGN

Eurovalve concept

Years of innovation, manufacturing and experience havecreated a complete range of centric rubberlined butterflyvalves.Up-to-date design and state of the art materials tailored tomarket needs and wishes such as no maintenance andlong service life. The Wouter Witzel design philosophy is

based on the principle objectives of achieving highreliability, high efficiency and to also be highly costeffective. High reliabilty by an excellent disc sealingconcept with a bonded rubber lining reducingmaintenance and downtime. High efficiency by excellentflow performance reducing energy losses.The diameter range is from DN 50 - 2000 (2 -80) and awide variety of materials is available for manyapplications. The valves are designed according to thelatest international standards and meet environmentalrequirements.

Design of the Eurovalve concept

The valve body is principally a cylindrical shape designedas a pressure containing part. The body is fullyrubberlined inside for sealing and corrosion protection.The body has flanges, lugs, or end connections formounting between pipe flanges and two necks for holdingthe shafts. The upper shaft extends out of the body and isused to operate the disc by the actuation device, mountedon a standardized interface flange.The disc is basically a circular part, which can rotate 90 on the axis of the shaft. The outer edge of the disc sealsagainst the lining in the closed position of the valve.

When the disc is perpendicular to the pipeline, the valve isshut. When the disc is parallel with the pipe, the valve isfully open. The orientation of the disc is indicated by agroove at the shaft end that is in line with the disc.Additionally the lever position or position indicator of theactuator shows the disc orientation.

High efficiency by low profistreamlined discs

Wouter Witzel has developed fuwith special low profiled and stresult in a low flow resistance wreduced energy costs for the endunder full-flow conditions the s

the diameter of the valve bore hon the fluid flow. Badly shapedvalves create pressure drop, turbpotential side effects such as vareduced plant efficiency. Attentstreamlining of the disc profile characteristics are to be achievecosts by selecting a Eurovalve minitial cost of the valve (ask Wocalculation)

High reliability by excellent

Wouter Witzel has developed a its Eurovalve ranges. The disc hwith the geometry of a centric laccurate and smooth-machined requires minimal deformation oto achieve a positive sealing. Thin less wear of the lining, a lowoperating torques.This excellent seating concept twhich is bonded to the valve bovalve performance, making thessuitable for high cycling freque

These features also make the Eusuitable for actuated duties.

Body lining materials

Wouter Witzel has invested heavily in research into formulation of rubber compounds and so developexpertise in rubber technology. The quality of rubber compounds is fundamental to the performance aEurovalve ranges.

Important: It is essential that for each individual case the selection of the type of rubber complies witcharacteristics .A wrong selection may cause failure of the valve. The given temperature limits shall be used as guide

of a type of rubber depends on the actual service conditions such as working pressure, peak temperatuof both the process fluids and any cleaning medium etc. In case of doubt please contact Wouter Witz

For detailed information about resistance / temperaturerange of the lining against fluids please contact Wouter Witze

Note: In addition to the above standard rubbers there are several optional materials to suit special duties.

2.6 TECHNICAL DATA

2.6.1 Flow data

ISOLATING VALVES (ON-OFF)Flow data of isolating valves is normally used within the calculations for pipework sizing and systemwhen the valve is in the fully open position. Many on/off isolating valves spend most of the time in and therefore these valves should have high Kv figures to reduce pressure drops, increase plant efficto reducing energy costs. Wouter Witzel has developed valves with a lot of attention being paid to aflow characteristics. (See table)

2.6.2 Valve operating torques

The operating torque of a butterfly valve is in general the result of four partial torques:1-Seating torque : Torque to overcome the rubberseat friction.2-Bearing friction torque : Torque to overcome the friction between shaft and bearing.3-Dynamic torque : Torque developed by pressure differences across a partly opened valv

flow velocities.4-Hydrostatic torque : Torque caused by the difference in static head of liquid on the valve d

the valve shaft in a horizontal position. (Only important for large valv

The operating torque of a valve under operating conditions may vary depending on different fluid aspec

it is important to submit the right fluid data (see Valve Data Sheet) to Wouter Witzel to avoid valve operto incorrect actuator sizing. When no information is available Wouter Witzel takes the following assumpactuator sizing: The fluid is water (without solid particles) in the temperature range of +1 up to 80 C. The fluid does not include chemicals or contamination that may increase the friction between the seat At least one operation cycle per month. Flow velocity in the pipe not more than 4 m/s.

Operating torques (Nm) at differential pressures under above mentioned conditions:

Notes: - DN 50 - 200 (2-8) are 16 bar rated valves.- Bigger sizes on request.

2.6.3 Mating flanges, compatibility

The Eurovalve ranges are designed for installation between flat or raised faced flanges with preference welding neck type according the following standards.

NOTE: It is important to specify the right PN number and flange standard when ordering.

2.8 STORAGE AND INSTALLATION

GeneralThis chapter gives general instructions regarding storage,installation and system testing of butterfly valves.For each type of valve Wouter Witzel has drafted a detaileduser manual with the following contents: Safety precautions Handling and storage Installation Operating conditions

Maintenance Trouble shootingAsk Wouter Witzel for a User Manual when ordering.

Storage of valvesStore the valve in dry, dark and cool conditions, preferablyindoors with the actual valve temperature higher than thedew point. If outdoor storage is unavoidable, support thevalves off the ground and protect the valves with awatertight cover.Do not remove the valve packaging or end portprotection, until necessary for inspection or installation.Store the valve in the slightly open position to avoiddeformation of the rubberlining.

Inspection prior to installation1 Inspect the valve visually for damage or contamination

during transport, handling and storage as this couldadversely affect valve performance.2 Carefully unpack the valve.3 Check the tagplates if attached on the valve.4 Inspect the valve interior and lining. It shall be clean,

free from foreign matter or damage.5 Check that all electric components are marked with the

correct IP rating and hazardous class when the valve isto be used in a hazardous location (explosive gas or

vapour).6 If practical, actuate the valve through close/open and

open/close cycles to check the correct function.Warning: Avoid contact with the valve disc.

Wouter Witzel supplies a wide selection of manual operators: lever and wormgear in different execuother options are available.

LeverThe basic manual operator for Eurovalves up to DN 200 (8 ) is the 10 position spring loadedprovides quick operation, economy and simplicity. When the lever is not in manual control it alwayposition.It is designed to open or close the valve or to regulate the flow. The lever is also designed to serve aindicator. When the lever is positioned parallel to the pipeline the valve is open.

WormgearTo reduce the required manual effort applied to operate a Eurovalve larger than DN 150 (6wormgear allows greater ease of operation and gives a better protection against system damage causdue to quick closing. For regulating valves with a wormgear the system can be properly balanced byCasing materials are aluminium or cast iron.

4 PRODUCT DATA: CHECK VALVES

FLANGELESS WAFER TYPE, RUBBER SEATED

4.1 GENERALFunctionThe ECV is a check valve to avoid unwanted back flow ina pipe.

ApplicationsIn water supply systems (distribution, treatment etc.),

irrigation, heating systems, ship building, industrialprocesses (liquids and gases).Temperature indication: EPDM -30 C to 110 C

NBR 0C to 90 C

Pipe connectionThe ECV check valve has been designed for installation inflanged piping systems (PN 10, PN 16, etc.).The flangeless wafer type body shall be clamped betweentwo flanges with flat or raised faces (weld neck or slip onflanges). Suitable gaskets shall be used for sealingbetween valve and flanges.

4.2 DESIGNThe ECV is a self acting pivoting check valve of the doubledisc wafer type. The valve is maintenance free. The designis compact and space saving.

The ECV check valve has a superior closing response priorto flow reversal. The corrosion resistant springs aredesigned to quickly close the valve at zero flow to prevent

undesirable pressure surges. In the closed position thevalve is tight shut off. It opens automatically when theflow starts again.

The elastomer seat is vulcanized and bonded to the bodyti g It i t f th fl th th i g t d d
