Ball Type Check Valve
Product overview
The HQ41X Ball check valve uses a rubber-coated roller ball as a flap. Under the action of the medium, it can roll up, down, left, and right on the integrated slide in the valve body to open or close the valve. Silent closure, no water hammer, good sealing performance. The valve body adopts a full water flow channel, with large flow rate and small resistance, and the head loss is 50% smaller than the swing type. It can be installed horizontally or vertically. It can be used in cold water, hot water, industrial and domestic water pipe network systems. It is more suitable for submersible sewage pumps. The medium temperature is 0~80℃.
Product Features
1. The valve body adopts full channel and streamline design, with small fluid resistance and large flow rate.
2. The joint of body, cover and piston rod is double sealed by sealing gasket and sealing ring without leakage.
3. Double guide of valve body, piston cylinder and piston ensures stable and reliable movement.
4. All stainless steel piston cylinder, integral casting piston and NBR sealing ring. Perfect combination greatly prolongs service life.
5. The detachable valve seat with advanced technology has ingenious structure, novel conception and convenient maintenance and replacement.
6. For the piston cylinder with guide hole, properly increase the resistance to make the piston movement more stable.
