Check the ratings given in the instructionsand on the product to make sure theproduct is suitable for your application.3. The installation has to be carried out byqualified personnel only.4. Carry out a thorough checkout wheninstallation is completed.WARNING∙Turn off gas supply before installation.∙Disconnect power supply to the valveactuator before beginning the installation toprevent electrical shock and damage to theequipment.∙Do not remove the seal over valve inlet and outlet until ready to connect piping.∙The valve must be installed so that the arrow on the valve points in the direction ofthe gas flow (gas pressure helps to closethe valve). Maintenance and serviceThe designed lifetime* of this product is 10 years, based on date code, according to:a) the standard EN 126b) the table on designed lifetime as stated onthe Afecor website /We cannot assume that the product can be safely used beyond the mentioned designed lifetime. This lifetime is based on use of the control according manufacturer’s instructions.Regular inspection of the control by authorized personnel in accordance with guidelines of the appliance manufacturer is required.After reaching the designed lifetime the product has to be replaced by authorized personnel.Note: * Warranty as opposed to designed lifetime is described in the delivery terms.Mounting positionThe gas valve can be mounted in vertical position with the coils at top side. The gas valve can be mounted plus or minus 90 degrees from the vertical.Mounting locationThe distance between the gas valve and thewall/ground must be at least 30 mm.Main gas connection flanged valves1. Take care that dirt does not enter the gasvalve during handling.2. Remove the flanges from the valve.3. Use a sound taper fitting with threadaccording to ISO 7-1 or new, properlyreamed pipe, free from swarf.4. Apply a moderate amount of good qualitythread compound to the pipe for fitting only;leaving the two end threads bare, PTFEtape may be used as an alternative.5. Screw the flanges onto the pipes.6.

Open the required gas flow channels byremoving the suitable plugs from the valvebody.2. Take care that dirt can not enter the gasvalve during handling3. Install the screw-in additional hardware asrequired (vent, by-pass, external pilotvalve)4. Please refer to the relevant instructionsheetCONSTRUCTION AND WORKINGPRINCIPLESThe VQ400M combination gas valves are 2 x class “A” fail safe shut-off valves. The valve is opened by energizing the direct ON / OFF operator. The direct ON / OFF operator consists of a coil and stopsleeve assembly. Inside the top sleeve assembly a plunger is placed which is able to move up anddown and thus opening or closing the valve. Theplunger is gliding on two anti-friction bearings. Flow regulation is done by adjustable plunger stroke. A strainer made out of steel AISI 303 is incorporated between inlet flange and main body.

Both sealants are available in small packages for maintenance and reapplication.hawkeye offers three material options for the pressure / vacuum seal, beyond the standard Fkm (viton®) seal.• For applications where sealing is the first priority and the vent is not expected to operate often and has low set pressures (under 4 ozsi), eFkm (sponge viton®) can be supplied.• For higher temperature, minimally freezing conditions and acid service FePm (aflas®) is available.• For extreme applications FFkm (kalrez®) is also available.the use of ePDm seals in any hawkeye vent is contra-indicated due to its unsuitability in common petrochem-ical applications.hawkeye does not offer or recommend using solid fluoropolymer (PtFe, PFa, FeP, etc.), nor expanded flu-ropolymer (gOre-tex®) as a gasket material and any venting device. although the material may be chemi-cally suitable, the harder crystalline polymer structure of these materials impedes sealing at the typically low interfacial pressures found in the marsh hawk, as well as other low-pressure (i.e. <15 psi) vents.GENE R A L FLU OROEL A STOM E R CHEM ICA L C OM PATI BI LI T Y¹FKM / VI TON N.B.¹ THIS CHART I S F OR R EFE REN CE ONLY.
