Ball type check valve adopts rubber coated rolling ball as the valve. Under the action of medium, it can roll up and down on the integral slide way of the valve body, so as to open or close the valve, with good sealing performance, closed in a silent way, without water hammer.The body adopts full flow channel with large flow, small resistance and head loss 50% less than that of swing type. It can be installed horizontally or vertically. It can be used for cold water, hot water, industrial and domestic sewage pipe network, and it is more suitable for submersible sewage pump with medium temperature of 0-80 ℃. It can be installed at the water outlet of the water pump to prevent backflow and water hammer from damaging the pump.
