Product Overview
In high-reliability gas systems, safety valves are used to release excess pressure under abnormal operating conditions, protect pipelines and critical equipment, and ensure stable closure after pressure recovery.
Our 4mm gas safety valves are specifically designed for inert gases such as nitrogen and helium, and are suitable for applications requiring high levels of sealing, reseating reliability, and environmental adaptability.
