Product overview
ARKA AS90NRV 3 Inch Flanged Check Valve is offered for application-based water-system selection in Sabah. Forward water pressure opens the non-return element. A loss or reversal of the pressure differential closes it to limit reverse flow. Match the model to the required water quality, pipe connections, operating pressure and flow.
