The DUNGS Dual Modular Valve (DMV-D(LE)/604) combines two normally closed, automatic shutoff valves in one compact housing (Rated as a NEMA Type 4x enclosure), which can be wired independently or in parallel.

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.
