CF8 PN40 Wafer Disco Check Valve For Petroleum Or Vapour , SUS304 Single Disc
Application:
Valve is used for preventing the back-going of medium in pipelines and equipments, and the pressure
of medium will bring the result of opening and closing automatically.
When the medium is back-going, valve disc will automaticaly closed to avoid accidents.
