Safety Solenoid Valve Manufacturer in China
This gas safety solenoid valve. When the gas alarm detects a gas leak, it sends a signal to the safety solenoid valve to quickly cut off the gas source to avoid the gas leak concentration reaching the explosion limit, thus preventing gas explosion accidents.
“To do a job well, one must first sharpen their tools.” Liang Zhengren is well-versed in this. Good management, good ideas, and good talent must be accompanied by excellent equipment to enable a company to truly have a strong production capacity and ensure the excellent quality of products. Liangzheng has more than 400 pieces of equipment.
Segmented Products of Safety Solenoid Valve

The normally closed gas safety solenoidal valve is a safety device in the gas transmission and distribution system.

The EV and EV/6B solenoid valves are normally closed valves. It is ensured that the valve is opened by the electric electromagnetic coil, and these valves are designed to start the valve to cut off the gas when the sensor is on the air side, or there is a gas leakage or power interruption.
Characteristics of Safety Solenoid Valve
Under the working conditions of the safety solenoid valve policy, the internal circuit of the electromagnetic valve is transformed into a very low guaranteed voltage, significantly reducing power consumption.
In low-voltage operation, the safety risks of electrical systems (such as overheating causing fires, short circuits, etc.) are significantly reduced, enhancing the overall system’s safety and compliance with industrial safety standards.

Safety Solenoid Valve Application Scenarios

When the gas alarm detects a gas leak, it sends an action signal to the electromagnetic valve to quickly cut off the gas source. To prevent leaked gas concentrations from reaching explosive limits and eliminates the possibility of gas explosions.

When there is gas leakage or an unexpected power outage, the valve will quickly close and cut off the gas source, preventing gas explosion accidents and ensuring the safety of users.

When the gas leakage alarm is triggered, only a momentary power signal is needed, or the electricity can be quickly shut off when the power is out.
Magnetic valve, safe and reliable. Excellent sealing performance, zero leakage.

Testimonial
Gas-fired boiler room, natural gas filling station, kitchen operation room using natural gas, factory workshop using flammable gas, etc.
The electromagnetic magnet of this safety solenoid valve is upright and upward, and the surface of the valve body is aligned with the flow direction of the gas medium to avoid rain, splashing water, and a humid environment.
Safety Electromagnetic Valve Benchmark
When working normally, the safety solenoid valve converts the internal circuit into a very low holding voltage after opening the valve. It reduces the coil temperature of the safety solenoid valve and saves electricity. After the gas leakage alarm, it only needs an instant power signal or can quickly close the safety solenoid valve after a power outage. It is safe and reliable, with excellent sealing performance and zero leakage.
In addition, in order to ensure a high level of safety, these valves can only be used when the circuit is powered on and the gas sensor does not detect any danger (positive safety feature).
