Elektrogas Safety shut off valves for gas with a hydraulic actuator  DN65 –  DN300

The Elektrogas VMH type valve is a safety shut off valve for gas with a hydraulic actuator. It is suitable for air or gas blocking and releasing controls, required in the main pipe of gas power burners, atmospheric gas boilers, industrial kilns, and other gas-consuming appliances.


  • The valves are made of aluminum alloy with a range for connections from DN 65 up to DN 300.
  • Pipe connections meet group 2.
  • Suitable for use with air and non-aggressive gases included in the 1st, 2nd and 3rd families (EN437).
  • Special versions for aggressive gases.
  • The valve is open only when energized: if, for any reason, power supply goes down, the valve
    closes immediately (intrinsic safe).
  • Qualified for continuous service (100% ED).
  • Size DN65-80 is equipped with a flow rate adjustment.
  • An incorporated fine mesh filter protects the valve seat and disc as well as downstream components and prevents dirty contamination.
  • Provided with the G1/4″ pressure gauge on two sides in both inlet and outlet chamber to connect manometers, pressure switches, leakage tester or other gas equipment.
  • The actuator is provided with ISO 4400 plug for easy cabling. The protection class is IP65 (EN
  • The actuator is provided with a led to visualize when it is energized.
  • All components are designed to withstand any mechanical, chemical and thermal condition
    occurring during typical service. Effective impregnation and surface treatments have been used
    to improve mechanical sturdiness, sealing, and resistance to corrosion of the components.
  • Valves are 100% tested and fully warranted.
