**Product Specifications:** 1) **Fluid Compatibility:** Natural Gas, Coal Gas, Liquefied Petroleum Gas (LPG) 2) **Size Range:** 25mm to 400mm 3) **Operating Temperature:** -20°C to 60°C 4) **Maximum Working Pressure:** Up to 500 mbar or 6 bar 5) **Body Material Options:** Stainless Steel, Cast Steel, Alloy Aluminum 6) **Response Time:** Less than 1 second **Key Features:** - Widely used in gas pipeline systems for safe and efficient control - Explosion-proof design suitable for hazardous environments - Low power consumption: Normally open type, only requires a brief electrical pulse to close - High safety and reliability: Once closed, it self-locks without the need for continuous power - Easy manual reset function allows for quick recovery after shutdown **Working Principle:** This solenoid valve operates in a normally open mode with a pulse-trigger mechanism. It features a self-locking function and manual reset capability for emergency situations. When the coil is energized, the plunger loses support and the spring force causes the valve to close quickly and lock in place. Even after the power is removed, the valve remains closed until manually reset by pulling the plunger back up. **Product Images:**
This gas solenoid valve is ideal for industrial applications where safety, reliability, and efficiency are critical. Its robust construction and advanced design make it a trusted choice for gas control systems in various industries.
