Swing check valves are essential components in fluid systems, designed to prevent reverse flow by automatically closing when the fluid direction reverses. Pressure seal swing check valves are used in high-pressure applications, ensuring a secure and tight seal, while welded bonnet check valves offer a leak-proof design for critical systems. The piston-type check valves are ideal for ensuring a smooth flow with minimal resistance, while bolted cover swing check valves provide easy access for maintenance.



There are various specialized check valves for different requirements. Lift check valves and dual plate check valves are commonly used in high-pressure systems due to their durability and effective flow control. Tilting disc check valves are designed to handle fluctuating pressures, while wafer-type check valves offer a compact solution for space-limited installations. Lockable swing check valves add security by preventing unauthorized operation, and double flanged check valves ensure secure connections in demanding environments.



High-performance check valves like the non-slam check valve, which minimizes water hammer, and zero leakage check valves are critical for industries requiring precision and reliability. Axial flow check valves are known for their streamlined design, reducing flow turbulence. Additionally, rubber-lined check valves and P.T.F.E.-lined check valves are tailored for corrosive media handling, providing enhanced protection and longevity in harsh environments. Silent check valves operate quietly, making them suitable for HVAC and residential water systems.
