Check valve, tilting seat, buffering type, ductile iron

Model Number: H47-9 Key Specifications/Special Features: Product descriptions: tilting seat buffering check valveFeaturesThe valve 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 valve is closed by the reversing flow medium and the weight and there is a damper on the valve. The valve is closed by two stages of quick and slow closing which prevents the pump fromturning back and super high water hammer pressure. The weight on the shaft balance the force during opening to reduce the flow resistance. Suitable medium：water、sea water Main materials： grey cast iron,ductile cast
