Nozzle Check Valves | Cast Flow

Cast Flow Valves

Cast Flow Nozzle Check Valve The Cast Flow Nozzle is an axial flow check valve with a short-stroke disc and return spring. The nozzle-type geometry channels flow through a Venturi effect, reducing pressure drop compared to conventional swing or dual plate designs, depending on body size and configuration. Operation is driven by differential pressure; no...
