Dual Modular Safety Shutoff Valves w/ Proof of Closure and NEMA Type 4x Enclosure DMV-D(LE) 704/624, DMV-D(LE) 704/634
The Dual Modular Valve DMV/624 combines two automatic shutoff valves in one compact housing. Valve 2 incorporates proof of closure. The DMV/634 combines two automatic shutoff valves in one compact housing. Valve 1 and Valve 2 incorporate proof of closure. Valve 1 (V1) of the DMV-D and DMV-DLE series is fast opening and fast closing. Valve 2 (V2) of the DMV-D is fast opening, while V2 of the DMV-DLE is slow-opening for smoother light-off. Max. flow adjustment on V2 provides variable main flow on both models. Internal profiles and compact design optimize flow and provide a low pressure drop.
Application: The DMV is recommended for industrial and commercial heating applications that require two safety shutoff valves with proof of closure. The DMV Dual Modular Valve is suitable for natural gas, propane, butane, air and inert gases. The DMV is suitable for dry natural gas, propane, butane, air and inert gases.
A “dry” gas has a dew point lower than +15° F and its relative humidity is less than 60%.
