ODM China Suppliers Factory JYFJS-011 Aluminum Alloy Electromagnetic Shut-off Valve for Gas Pipeline Safety Supplier, Suppliers
Product Description
This valve is a normally open shut-off valve with a holding control mode. It remains open without power during normal operation and can automatically close upon receiving a shut-off signal. After closing, it can be manually opened and will automatically close again upon receiving another shut-off signal.
When a leakage accident occurs, the alarm system sounds an alert, instantly providing a DC pulse voltage to the solenoid valve. The coil is energized, driving the valve to quickly close, cutting off the gas source and entering a self-locking state.
When a gas leak occurs, the alarm's capacitor continuously releases a 3-second DC pulse voltage, energizing the coil, closing the valve to cut off the gas supply, and entering a self-locking state.
The interaction of instantaneous electromagnetic force of the coil, permanent magnetic force, and spring force is used to achieve pulse drive, automatic valve closing, and manual valve opening self-holding functions.
