Product Description
Swing Check Valve Features:
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 from
Turning back and superhigh water hammer pressure. The weight on the shaft balance the force during opening to reduce the flow resistance
This kind of valves are automatic type which are opened by the pressure of the medium and closed by the reversing flow. The water hammer rising has been taken into consideration during design so it is reliable.
