DUAL DOUBLE
NON-RETURN VALVE 
DDNRV

DUAL’s Double Non-Return Valve operates on the discharge side of two pumps in parallel. Both pumps can run simultaneously or independently.

DUAL SLIMLINE BALL NON-RETURN VALVE 
DSFFV

As the pump stops, the ball falls and positively locates the seat due to its own weight and back pressure of the liquid. This results in drop-less sealing.
