CIRCOR Valve Alternative

CIRCOR International Inc. (now IMI plc)

CIRCOR International (acquired by IMI plc in 2023) manufactured a range of high-pressure valve products including the Leslie steam conditioning valve brand, Circle Seal check valves and high-pressure needle valves, and Dynisco process valves. CIRCOR's Leslie valves are widely specified in steam conditioning and pressure reducing applications in power plants. The Circle Seal instrumentation valve range is used in high-pressure gas and hydraulic service. Vajra Industrial Solutions supplies equivalent high-pressure needle valves, instrumentation manifolds, and steam conditioning globe valves.

Legal DisclaimerCIRCOR, Leslie, and Circle Seal are trademarks of CIRCOR International / IMI plc. Vajra Industrial Solutions is not affiliated with CIRCOR or IMI. Steam conditioning valve replacements require engineering review of desuperheat capacity and trim characteristics.

Why Consider CIRCOR Alternatives?

Post-IMI acquisition pricing for Leslie steam valves has increased significantly
Circle Seal needle valve alternatives available at substantial cost saving
Lead times from IMI/CIRCOR extended to 16–24 weeks for specials
Steam conditioning valve market has more competitive alternatives than ever
