Description
1. Overview of Gas Solenoid Valve
Gas solenoid valves are designed to control the flow of gas using electromagnetic principles. They are commonly used in gas systems for safety and efficiency, including applications in gas furnaces, water heaters, and boilers.
Key Applications:
- Paired with combustible gas leakage monitoring instruments to automatically shut off the gas supply during leaks.
- Integrated with gas leakage alarms to provide rapid shutoff within 1 second when a leak or emergency is detected.
- Available in normally open configurations, allowing manual reset after resolving safety hazards.
