Description
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 DMVDLE 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.
Directly mounting the following accessories creates a compact valve train without additional piping: High and low gas pressure switches,Vent line adapter, DMK butterfly control valve, and VPS valve proving system.
Application
The DMV is recommended for industrial and commercial heating applications that require two safety shutoff valves with proof of closure. The DMV Dual ModularValve 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 %.
