Slow Close muffler check valve
Mainly used for industrial and urban water supply and drainage pipeline and high-rise residential, senior hotel, pressure lose water pump outlet. On the design fully consider the use environment requirements, the inclined plate structure, to achieve no vibration, no noise, smooth operation, ensure that the hotel, residential environment quiet. And has the effect of energy saving. With slow close way to make local backwashing water in the system to discharge. Thus greatly reduces the stop pump refluent hydraulic impact, eliminate the destructive water hammer peak production, intercepting seal using acrylonitrile butadiene rubber, sealed performance is good, shock wear-resisting, long service life, easy maintenance, etc.
