Gas Emergency Shut off Solenoid Valves


  • 1.There are two ways to close the valve:
  • (a)An electric impulse of 1 sec (DC 9V)or
  • (b)Press the red knob (must open the protective cover first ). After this operationthe valve remains closed.
  • Note: the protective cover must remain on position at all time.
  • 2.When the valves is closedmanually pull the red knob up to turn it on .then the valve remains on.
  • Note: the valve may not to be pulled up if gas pressure on both sides(inlet and outlet) is not balanced. Take necessary action to ensure that they are balancedthen pull the knob up againforce pulling it may result in damage to the valve.
  • 3.The valve will close automatically when it detects strong vibrations. Should this feature failsnotify the contractor or manufacture for repair.
  • 4.After closingcareful inspection is required.Do exercise caution when the valve needs to be turned on again.

Installation Requirements

  • Only request contractor can install this valve.
  • The valve must be installed after the indoor main valve.
  • A valve should be installed in the gas flow direction marked on the valve body. The coil must not be placed in downward position A valve may be installed horizontally or vertically.
  • the valve control wires should be connected correctly. White indicates positive while black stands for negative. Mismatch lends to fatal consequences.
  • During pipe maintenancesuch as pressurized pipe cleaning .the valve should removed to avoid damages to the valve sealing.
  • During pressure teststhe valve should be turned on.
  • The valve's opening knob can be pulled up when equal pressure have been reached at the inler and the outlet of the valve.
  • Wrong polaritywrong voltage or prolonged power on may damage the electromagnetic coil.
  • Our guarantee does not include any damage to the valve or loss of parts due to keeping or actions in violative regulations.
