Copper Check Valves are generally made from commercially pure copper or copper alloys, providing outstanding corrosion resistance and solid mechanical properties. The tensile strength of copper ranges from 210 to 275 MPa, and its high ductility and malleability make it easy to work with for leak-tight seals. These valves are tailored for low- to moderate-pressure applications and excel at preventing reverse flow in domestic water lines, HVAC systems, and chilled water circuits. Paul Tube Fittings guarantees precision manufacturing, ensuring smooth valve operation, corrosion-resistant internals, and compatibility with copper piping systems for durability and minimal upkeep.
