DUNGS Dual Modular Safety Shutoff Valves DMV..525 Series

The DMV is recommended for industrial and commercial heating applications that require two safety shutoff valves. The DMV is suitable for dry natural gas, propane, butane, air and inert gases. Suitable for up to 0.1% by volume, dry H2S.

The 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 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 accessories creates a compact valve train without additional piping:

  • High and low gas pressure switches
  • Valve proving system
  • DMK Butterfly control valve
  • 1” NPT Vent line adapter

Max. Operating pressure: 7 PSI (500mbar) / 5 PSI (360mbar)
