H76 Wafer Type Dual Disk Swing Check Valve , Made By Ductile Iron , SS Plate
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.
material: WCB,CF3,CF8,CF3M,CF8M |
