Product details
Working principle:Piston type gas emergency shut-off valveNormally open type—This product is generally used in conjunction with gas leak alarms. In the event of a gas leak or emergency shutdown, the host sends a pulse power signal to the solenoid valve, which cuts off the gas supply within 1 second, effectively preventing accidents. After eliminating the danger, the protective cover is manually unscrewed and the handle ball is lifted up to open the valve!
Piston type gas emergency shut-off valve normally closed - in the working state, the solenoid valve is in the open state, and the coil is also in the live state. When gas leakage or power outage occurs, the solenoid valve will instantly cut off the gas source; When turning on, first lift the handle ball to position, and then turn on the power. The disadvantage is that the solenoid valve cannot be opened during a power outage.Detailed parameters:

Performance characteristics:High sensitivity, strong dynamic sealing, high safety, and long service life.
ConnectionThe yellow line is the ground wire (optional), and the other two are not divided into positive and negative poles.
Scope of work:Combustible gas alarm self-control system and pipelines that require emergency shutdown.
Annotation:1Piston type gas emergency shut-off valveBefore installation, impurities and welding slag inside the pipeline must be cleaned to prevent leakage inside the valve body.
2Piston type gas emergency shut-off valveUnder normal working conditions, it can only be installed horizontally. When installing vertically, it needs to be explained in advance.
3Piston type gas emergency shut-off valveAfter installation, it should be operated several times before it can be put into use.
Explosion proof coil description: Explosion proof solenoid valves are solenoid valves that operate in relatively special environments, and users must choose solenoid valves according to national explosion-proof standards. To ensure the safety of life and property. The explosion-proof solenoid valve produced has passed the inspection of the National Explosion proof Electrical Product Quality Supervision and Inspection Center and obtained the explosion-proof solenoid valve product qualification certificate.
Explosion proof grade:EXd Ⅱ CT4. Explosion proof certificate number:CNEX12.0353
Manufacturing standards:GB3836.1-2000、GB3836.2-2000
