Check Valves
Check valves are designed to prevent return flow by closing automatically through fluid pressure, ensuring unidirectional flow in piping systems.
Available in swing, non-slam, and wafer types, check valves in cast and forged steel are vital in industries like oil and gas, water treatment, and power generation for reliable backflow prevention.
Check valves operate without external control, relying on fluid pressure to open and close, preventing reverse flow that could damage equipment. Swing and non-slam check valves, available in cast and forged steel, are suited for high-pressure systems, while wafer check valves, designed to API 594, offer a compact solution for space-constrained applications. Their robust design and versatile connection options make them essential for maintaining system integrity in critical industrial processes.
Check valves are manufactured to meet rigorous industry standards, ensuring performance and compatibility in various systems.
