The spherical check valve HQ41X-16Q adopts a rubber wrapped rolling ball as the valve disc. Under the action of the medium, it can roll up and down on the integral slide of the valve body, thereby opening or closing the valve. It has good sealing performance, noise reduction, and no water hammer. The valve body adopts a full water flow channel, with high flow rate and low resistance. The loss of the faucet is 50% less than that of the rotary valve. It can be installed horizontally or vertically and can be used in cold water, hot water, industrial and domestic sewage pipelines. It is more suitable for submersible sewage pumps, with a medium temperature of 0-80 ¡æ. Can be installed at the water pump outlet to prevent back flow and water hammer damage to the pump.
