DRV7 and DRV7G SG Iron Pressure Reducing Valves
Direct-acting pressure reducing valve in nodular cast iron with sealing bellows membrane. The standard version has a membrane in EPDM and is suitable for steam, water, and compressed air. The DRV7 is available with a membrane made of nitrile (suffix N) suitable for oil.
A version with a soft seal in nitrile (suffix G) is available for optimal sealing (limited to 90C, maximum pressure ratio 10:1). For steam, a water lock vessel type WS4 must be installed in the impulse line to protect the membrane.
