Retainerless Wafer Type Tilting Disc Check Valve-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.
The different materials selection can apply to the medium involving water, steam, oils, nitric acid, acetid, strong oxidizing medium and urea etc.
Structural Feature
Valve disc closedown quickly,low water hammer pressure;
Applicable for and easily installed for vertical or horizontal pipelines;
Smooth flow passageway and small fluid resistance;
Flexible action and good sealing performance;
Narrow valve travel and small closedown impact;
Integrated structure,simple and compact,in beautiful shape;
Long service life and good reliability.
Offset structure, with optimal face to face length which reduces flow resistance and eliminate pressure surge.to be used for protecting from medium backflowing.
