Aluminum bronze lift check valve
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.
Product Structure Characteristics
Traditionally, Aluminum bronze swing check valves have been manufactured with bronze clapper arm shafts. Under severe service conditions where grit or sand has been present, these bronze shafts have a tendency to wear.Aluminum bronze swing check valves incorporate the following design features to help increase service life. Bodies and Bonnets Valve bodies and bonnets are made of gray iron.
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.
