RAQ Series Gas Shut-off Valve

Product Application

It is used for emergency shut-off protection in gas transmission and distribution systems to monitor gas pressure. When the system pressure exceeds the set value, the shut-off valve can quickly cut off the gas supply (manual reset required).

Product Features

The shut-off valve requires no external power supply and operates using the pipeline’s own pressure. It delivers high actuation accuracy and fast response speed, and can work normally in relatively dirty gas media. Installation, commissioning, operation and maintenance are simple and convenient.
