300x Slow Closing Noise Elimination Check Valve - Dn50-dn600 Port Size, Medium Pressure 1.0-2.5 Mpa | Manual Control, Soft Seal, 0-80°c Temperature Range

Backed by rich industry experiences, we "Botou Feng Sheng Automatic Control Valve" are leading Exporter of 300X Slow Closing Noise Elimination Check Valve in Botou, Hebei, China.
300X slow closing check valve controls the speed of opening and closing. When starting or stopping the pump running, it can adjust to the best opening or closing speed with the field. Can be used in high-rise buildings, reducing water hammer and water hammer phenomenon, so as to achieve the effect of quiet closed. A
Installation:
1 H300x series check valves are available horizontally and vertically. A
2 check valve should be cleaned before the installation of impurities in the pipe network to ensure the normal operation of the valve. A
