Dual Swing Check Valve (DSCV)
Dual Swing Check Valve (DSCV)
Dual’s Swing Check Valves embody which is designed to swing out of the line of fluid flow at maximum capacity. The seat is off-set from horizontal and is hinge positioned so that the gravitational action causes the valve to close in proportion to the reduction in fluid flow. The valves can be installed either vertically or horizontally.
As an optional extra, an extended hinge pin permits the fitting of an outside lever and weight to effect closure immediately, thereby eliminating slamming. A door position indicator can also be fitted.
Rubber disc valves suitable for pressures up to 1000kPa are also available.
