Oil Service Wafer Check Valve
Small in size , light in weight ,compact in structure ,easy in maintenance.
Twotorsion spring are added to each of the pair valve ,plates which close the plates quickly and automatically.
The quick-close action prevents the medium froming back.
Short face to face and good rigidity.
Easy installation .it can be installed on both horizontal and vertical direction pipelines.
This valve is tightly sealed .without leakage under the water pressure test .
Safe and relianble in operation .,hihg n terference - resistance .
