Product Introduction

Pipeline gas self-closing valve is an installation device installed at the end of indoor low-pressure gas pipeline and connected to indoor gas appliances through rubber hoses or metal bellows. When the gas pressure in the pipeline is lower or higher than the setting value, or when the hose is broken, falling off and causing loss of pressure, it can be automatically closed in time to prevent accidents. Manual reset is required after troubleshooting.

Technical Parameters

Major Features

Under-voltage anti-backfire

When the community pressure regulating station fails or the gas supply pressure is too low due to other reasons, which may cause flameout or backfire, the self-closing valve automatically shuts off the gas source to effectively control the insufficient gas source;

Overpressure protection

When the pressure regulating equipment fails and the air pressure suddenly rises beyond the safe range, this valve automatically cuts off the gas source to prevent the hose from rupturing and falling off due to high pressure, and the burning appliance is out of fire due to high pressure;

Superfluid cut-off

When the gas hose is loose, falling off, aging, rat bite, or ruptured, causing gas leakage, the self-closing valve automatically cuts off the gas source. After troubleshooting, pull up the valve stem to open the gas source.
