Dungs 267088 Dual Modular Valve 702/624L Series With Proof of Closure 120VAC

The DUNGS Dual Modular Valve (DMV-D(LE)/624; 634) with Proof of Closure combines all the features of the DUNGS Dual Modular Valve DMV/604 plus overtravel and a proof of closure switch which is factory mounted and set.  The Dual Modular Valve DMV/624L combines two automatic shutoff valves in one compact housing. Valve 2 (V2) incorporates proof of closure. 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 - Vent line adapter - Butterfly control valve
