Non-slam check valve NC500

for waterDINflange

Smooth action, without impact Easy regulating and maintenance Excellent and reliable sealing performance Controllable opening and closing speed Built-in strainer, to prevent the piping system from blocking NC500 silencing non-slam check valve is a hydraulically controlled diaphragm valve with controllable opening and closing speed. When inlet pressure rises and exceeds the valve opening pressure, the valve will open slowly to avoid impact. When the back pressure is generated, the fluid will enter the air chamber of the valve, and the valve will close slowly to form a tight seal. The opening and closing speed can be adjusted by the opening angle of the needle valve in the main pipe. The valve is particularly suitable for use in the occasions where absolute sealing is required. Its rubber seal ring can ensure that the valve is free from leakage. In addition, the simple design of the valve can also ensure reliability. Please Provide the Following Data When Ordering Valve figure number/size/pressure grade/connecting end type/other optional accessories Note: In valve installation, it is strongly suggested that sufficient space should be left for easy maintenance in the future. A strainer shall be mounted in front of the valve to prevent foreign matters from blocking the valve.
