Description
The Dual Modular Valve (DMV) combines two automatic shutoff valves in one compact housing, which 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. Three 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
