The ball type check valve is used as a flap with a rubber foreskin ball. Under the action of the medium, it can be rolled up and down on the integral slide of the valve body, thereby opening or closing the valve, the sealing performance is good, the muffling is closed, no Water hammer. The valve body uses a full water flow channel, small flow, small resistance. The water head loss is smaller than the rotor, horizontal or vertical mounting can be used for cold water, hot water, industrial and domestic sewage official website, more suitable for sewage pumps.

The rubber ball can reduce the damage to the pipeline system in the process of valve closing, Ball type check valves have a long service life, are suitable for the installation environment that needs noise reduction, and the water quality requirements are not strict.
Long service life, stable operation, safe and reliable, and good sealing performance
The drag coefficient is small. Because it is a ball valve, the water flows almost straight through the valve body.
The shock absorption effect is good, and the requirements for water quality are not strict.
Ball check valves are mainly used in waterworks, municipal construction, sewage discharge, real estate, and other industries. It can be used in hot water, cold water, industrial and domestic sewage pipe networks. It is more suitable for submersible sewage pumps, and the operating temperature is 0-80 degrees Celsius.
