Dual Slurry Swing Check Valve (DSSCV)
Dual Slurry Swing Check Valve (DSSCV)
Dual’s Slurry Swing Check Valve operates on the discharge side of the pump as the flow through the pipeline starts or stops. The disc automatically rises and falls, opening and closing the valve. This occurs without noticeable shock or hammer, regardless of the line pressure or the speed of closure.
The Dual Slurry Swing Check Valve is particularly well suited for harsh highly abrasive flow control applications in liquid-solid and gas-solid pneumatic conveying services where long valve life and low maintenance are desired. The disc and seat are replaceable.
