ASME B16.34 Check Valve

186 products found

An ASME B16.34 check valve is a high-integrity backflow prevention valve designed in strict accordance with the foundational American Society of Mechanical Engineers standard for pressure-rated valves. As the industry's ultimate safety benchmark, ASME B16.34 dictates precise wall thicknesses, material classifications, non-destructive testing (NDT) criteria, and strict pressure-temperature ratings for the valve shell to ensure maximum structural integrity. Operating automatically via line pressure to permit unidirectional flow and prevent reverse backflow, these check valves are available in swing, piston, or ball configurations with flanged or welding ends. As a distinguished platform representing multiple China check valve manufacturers, we supply valves precision-machined and rigorously pressure-tested to comply with ASME B16.34 safety margins in full, providing certified, leak-tight operation and uncompromised reliability for the most demanding high-pressure global pipeline applications.
