Crown-Europa (Non-Slam) Nozzle Check Valve

Crown-Europa (Non-Slam) Nozzle Check Valve


The Crown-Europa (Non-Slam) Nozzle Check Valve is designed for severe service applications where fast reverse flow exists and conventional check valves are unsuitable for the existing flow conditions. In addition to a smaller footprint than conventional check valves, Crown-Europa (Non-Slam) Nozzle Check Valves also save energy due to their low pressure drop.
