Description

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
