The DUNGS Flanged Dual Modular Valve (DMV) combines two normally closed, automatic shutoff valves in one compact housing, which can be wired independently or in parallel. Valve 1 (V1) of the DMV, DMV-D and DMV-DLE series is fast opening and fast closing. Valve 2 (V2) of the DMV and DMV-D is fast opening, while V2 of the DMV-DLE is slow-opening for smoother light-off. Max. flow adjustment on V1 provides variable main flow on the DMV-D and DMV-DLE models.
Application
The DMV/11 is recommended for industrial and commercial heating applications that require two safety shutoff valves in series. The DMV is suitable for natural gas, propane, butane, air and other inert gases.
