Check Valves

Overview

Forged steel check valves are suitable for high-pressure flow control scenarios where there’s a need to prevent backflow. The mechanism within these valves — available in ball check, spring ball check, swing check, piston check, and spring piston check designs — is designed to ensure unidirectional flow of liquids, and the solid forged steel construction makes them suitable for use in demanding environments like oil and gas, chemical, and petrochemical plants.

Smith Piston Check Valves are available in non-spring loaded or spring loaded design in Class 150-1500 and feature conventional ports. Available in bolted or welded caps with either threaded, socketweld or RF ends. All are manufactured in accordance with API 602 and ASME B16.34 standards.
