“The DUNGS Dual Modular Valve (DMV) eco combines two safety shutoff valves in one compact housing, with an option for Proof of Closure on valve two or both valves.
Valve 1 (V1) of the DMV, 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.
Internal profiles and compact design optimize flow and provide a low pressure drop. Directly mounting the following DUNGS accessories creates a compact valve train without additional piping:
- High and low gas pressure switches
- Valve proving system
- 1″” NPT Vent line adapter
- Max. Operating pressure: 7 PSI
- Nominal diameter: ISO Flange 2 1/2" - 5"
