1-1/4" Gas Solenoid Valve, LPG/Natural Gas

Gas solenoid shut off valve uses NBR rubber sealing material to ensure good air tightness. The emergency gas shut off valve opening time is less than 1 second and is suitable for an operating temperature range of -10℃ to 50℃. The manual opening function facilitates quick response, and the valve closing can be driven by DC pulses or manually operated, with a closing time of less than 0.3 seconds.

Tips: Installation requirements of gas shut off solenoid valve

• The valve must be installed after the indoor main valve.
• A gas shut off solenoid 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 gas solenoid valve control wires should be connected correctly. White indicates positive while black stands for negative. Mismatch lends to fatal consequences.
• During pipe maintenance, such as pressurized pipe cleaning. The valve should remove to avoid damages to the valve sealing.
• During pressure tests, the gas shut off solenoid valve should be turned on.
• The valve's opening knob can be pulled up when equal pressure has been reached at the inlet and the outlet of the valve.
• Wrong polarity, wrong voltage or prolonged power on may damage the electromagnetic coil.
• Our guarantee does not include any damage to the gas solenoid valve or loss of parts due to violation compass operation.
