Tilting Hydraulic Operated Check Valve Double Fanged HR77
Tilting Disc Buffering Check Valve of the sealing surface is declined against the outlet with small dropping angle to reduce the vibration meanwhile there is buffering device in the body which can buffer by the flow to prevent the pump from turning back and super-high water hammer pressure.with hydraulic operated make its more flexible.
The different materials selection can apply to the medium involving water, steam, oils, nitric acid, acetid, strong oxidizing medium and urea etc.
