3/4" Gas Solenoid Valve, LPG/Natural Gas

The 3/4" gas solenoid valve is suitable for liquefied gas and natural gas, with an operating voltage range of DC 9-15V, providing flexible power supply options. The operating temperature range is -10℃ to 50℃. Its corrosion-resistant materials and excellent sealing performance ensure long-term stable use, suitable for home and industrial applications. Gas solenoid shut off valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.

Tips: The working principle of the gas solenoid valve

The working principle of gas solenoid shut off valve is based on electromagnetic force. When the power is turned on (usually DC 9-15V), the current passes through the coil to generate a magnetic field, which attracts the iron core inside the valve, causing the valve to open and allow gas to flow. When the power is cut off, the magnetic field disappears, the iron core is reset under the action of the spring, and the valve closes, cutting off the flow of gas.
