HQ45XThe micro resistance ball type check valve adopts the rubber covered ball as the valve disc. Under the action of medium, it can roll on the slide way in the valve body, so as to open or close the valve. It has the advantages of large flow rate, small flow resistance loss, good sealing performance, noise elimination and closing, which can reduce water hammer wave. It can be installed horizontally or vertically. It can be used for water pump outlet of cold water, hot water, industrial and domestic sewage pipe network to prevent medium backflow. The models of ball check valve produced by our company are: hq44x / hq45x.

The ball check valve has the advantages of large flow rate, small flow resistance loss, good sealing performance, silencing closing and reducing water hammer wave. It can be installed horizontally or vertically. Can be installed with cold water, hot water, industrial and domestic sewage and other official website pump outlet, to prevent the medium backflow. The valve has few parts and is easy to disassemble. The rubber layer of the ball has good elasticity and wear resistance, so it has vibration absorption, easy sealing and safe and reliable operation.
