The function of a check valve is to prevent the backflow of medium in the pipeline. Check valves belong to the category of automatic valves, and the opening and closing parts open or close themselves by the force of the flowing medium. Check valves are only used on pipelines with unidirectional flow of media to prevent media backflow and prevent accidents Product Description: main features  1. Middle flange structure (BB): The valve body and valve cover are connected by bolts, which is convenient for valve maintenance. 2. Middle welding: The valve body and cover adopt a welding structure, suitable for high-pressure working conditions. 3. Self sealing structure, suitable for high-pressure working conditions, with good sealing performance. 4. The channel of forged steel check valve body adopts full diameter or reduced diameter, and the default is reduced diameter. 5. Lift check valves, ball check valves, swing check valves, etc. 6. Springs can be installed as needed.

Aluminum bronze swing check valves are used in numerous applications where liquid must pass in only one direction for safety purposes and to prevent reverse flow. We offer several types of high-performance check valves in a range of functionality types, material construction, and sizes for commercial, process industries, and utilities.

Generous clearances are provided between the disc circumference and body, as well as the clapper hub and body, which prevent the possibility of binding. Internal contours are specifically designed to provide a smooth flow passage and reduce head loss through the valve. The entire clapper arm and disc assembly are easily removed through the bonnet opening while the valve is installed in the line. Clapper Arms The clapper arms are made of ductile iron. The clapper arm shaft hole and disc stud hole are bushed with bronze for wear and corrosion resistance. Clapper Arm Shafts Clapper arm shafts are made of high tensile strength, corrosion-resistant stainless steel.
