Seating force of Nozzle Check valves is faster than other check valves due to spring. When the valves are open, the Nozzle Check valves have outstanding stability for pressure because the Nozzle Check Valves consist of streamlined nozzle.
One of the features is to minimize any damages of water hammer. Moreover, it is possible to prevent damages of equipment from a back flow and reduce pressure loss of piping system. Also, the Nozzle check valves are assessable for both of vertical and horizontal piping.
The available sizes of the valve are from 2inch to 24inch on average and the pressure of the valves is bearable up to over 2,500 PSI.
