HQ41X Ball Check Valve
Overview
The HQ41X ball check valve is a type of valve that automatically opens and closes by relying on the pressure of the medium itself to drive the ball. Its core function is to prevent backflow of the medium in the pipeline and protect equipment such as pumps and compressors.
Features
The HQ41X ball check valve adopts a rubber-coated ball as its disc. Driven by the medium, the ball rolls along the valve body’s slide to open/close the valve. It boasts high flow rate, low flow resistance, reliable sealing, silent closure and reduced water hammer. Suitable for pump outlets in cold/hot water, industrial and domestic sewage systems to prevent medium backflow.
