Gas pipeline self-closing valve
The gas pipeline self-closing valve is a new type of safety device installed at the end of indoor low-pressure gas pipelines. It connects to gas appliances via a flexible hose (or alternatively, a metal corrugated pipe) and is designed to detect gas pressure, automatically shutting off the flow while requiring manual reset. Hanyu Xing’s latest-generation smart gas pipeline self-closing valve boasts advanced technology, zero energy consumption, zero pollution, manual operation, automatic shut-off in case of gas supply interruption, automatic shut-off upon detecting excessive gas leakage or overpressure, as well as automatic indoor pressure checks—all without the need for maintenance. Currently, this product is officially promoted by China’s Ministry of Construction (as featured in the China Gas Equipment Design Manual) and is recommended by the China Gas Association.
