DUNGS Combustion Controls manufactures a wide range of gas controls featuring: Single and Double Safety Shutoff Valves, Gas and Air Pressure Switches, Pressure Reducing and Ratio Regulators, Flow Control Valves, Actuators and Other Burner Equipment.



The DUNGS Dual Modular Valve system (DMV) combines two automatic 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. Three body styles reduce inventory.

Directly mounting system accessories creates a compact valve train without additional piping:
  • Pressure regulator.

  • High and low gas pressure switches.

  • Valve proving system.

  • Vent line adapter.


Applications

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