Water check valve NC300

DINflangefor pipelines

Smooth action, without impact Small volume and light weight Easy regulation and maintenance Excellent and reliable sealing performance Separately controllable opening and closing speed Built-in strainer, to prevent the guide piping system from being blocked NC300 silencing non-slam check valve is a hydraulically controlled diaphragm control valve with controllable opening and closing speed. When inlet pressure rises and exceeds the valve opening pressure, the valve will open gradually to avoid impact. When the back pressure is generated, the fluid will enter the air chamber of the valve, and the valve will close gradually to form a tight seal. The opening and closing speed can be adjusted by the opening angle of the guide piping needle valve. The valve is particularly suitable for use in the situations where absolute sealing is required. Its rubber seal ring can ensure that the valve is of no leakage. In addition, the simple design of the valve can also ensure its reliability. Please Provide the Following Data When Ordering Valve figure number/size/pressure grade/connecting end type/pressure regulating range/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.
