Natural Gas Special Check Valve
Introduction:
The special check valve is suitable for controlling the opening and closing device for connecting or cutting off the pipeline medium under various pressures, temperatures and media of medium and small diameter pipelines; Depending on the weight of the valve disc and the fluid pressure difference, the reverse flow of the fluid in the pipeline is automatically prevented
