Dual Modular Safety Shutoff Valves
DMV-D/11 Series
DMV-DLE/11 Series
DMV ISO FLANGED Sales Brochrue • P/N 242955 • Ed. 05/18
Description
The DUNGS Dual Modular Valve (DMV) combines two safety shutoff valves in one compact housing, 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 V1 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
