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 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 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
- Max. Operating pressure: 7 PSI
- Nominal diameter: DN 40 - DN 125
The DUNGS DMV is recommended for industrial and commercial heating aplications that require two safety shutoff valves. The DMV Dual Modular Valve is suitable for dry natural gas, propane, butane, air and other inert gases. Suitable for up to 0.1% by volume, dry H2 S.
A “dry” gas has a dew point lower than +15 ÁF and its relative humidity is less than 60 %.
