Ball check valve uses bowl classified covered by rubber as valve disc. With the help of medium, the valve disc can roll up-down or right-left to close or open valve. It can avoid water hammer and has good sealing. The valve body adopts the whole water channel, having large flow and low fluid resistance. Head loss is less than swing valve by 50%.

 Ball check valve can be installed vertically or horizontally. It can be used in pipe lines for cold water or hot water. It is quite suitable for diving drainage pump. Applicable temperature is 0~80℃.                 Technical Parameter:
