Pipeline Gas Self-closing Valve

Performance & Advantage Cut-off When Over-flow: If gas hose loses off, burns out, bit by rats or ruptures, causing its flow exceeds the set value, the valve will cut off the gas source automatically. Protection From Over-pressure: The safety valve will cut off the gas source automatically if the pressure regulator is out of work, or the air pressure suddenly rises and exceeds the safety pressure, making its flow exceeding the set value. Automatica Turnoff When Over-low Pressure(Anti-backfire): The protective valve will shut off the gas source automatically if the pressure regulator station is out of work or other situations, which lead to insufficient pressure supply of thegas pipeline, to prevent the backfire accidents from happening. Cut-off & Shut-off Function: The valve will cut off the gas source automatically, if fuel pipeline stops supplying gas due to unexpected events or corrective maintenance and so on. Micro-leakage Inspection Function: Close gas appliance switch, pull up self-closing valve kn
