Dungs 267061 Dual Modular Valve With Proof of Closure DMV-D 701/622 Series 120VAC

The Dual Modular Valve DMV/622 combines two automatic shutoff valves in one compact housing.Valve 2 (V2) incorporates “proof of closure” valve seal overtravel and interlock.Both valves can be wired independently or in parallel. 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.Two body styles reduce inventory. Directly mounting the following accessories creates a compact valve train without additional piping: - Pressure regulator - High and low gas pressure switches - Valve proving system - Butterfly control valve

The DMV/622 is recommended for industrial and commercial heating applications that require two safety shutoff valves and “proof of closure” valve seal overtravel and interlock.The DMV Dual Modular Valve 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 %.
