Valves that actually respond when your compressor needs them.
Inlet guide vanes, blow-off valves, anti-surge valves, and check valves — refurbished to OEM spec or supplied new. Proper valve response prevents surge, protects your machine, and saves energy.
Problems you might be facing
Surge events damaging your compressor
Sticky or slow-acting anti-surge valves putting your impellers, thrust bearings, and seals at risk of catastrophic failure.
Valves sticking or hunting
Inlet guide vanes that don't modulate smoothly — causing inefficient operation, pressure swings, and wasted energy.
Blow-off valve leakage
Worn blow-off valves venting compressed air continuously — costing thousands in wasted energy per year.
Capabilities
Inlet guide vanes (IGVs)
Multi-vane and single-vane IGV assemblies with pneumatic or electric actuators for precise capacity control.
Anti-surge valves
Fast-acting recycle valves with <1 second stroke time — sized and tuned for your compressor's surge map.
Blow-off valves (BOVs)
Atmospheric discharge valves — rebuilt with new seats, seals, and actuator diaphragms for zero-leak shutoff.
Check valves
Discharge check valves preventing reverse rotation on shutdown — spring-loaded and wafer-style options.
Actuators & positioners
Pneumatic and electro-pneumatic actuators with digital positioners for precise valve positioning.
Valve refurbishment
Complete strip, inspect, and rebuild service — seats re-lapped, seals replaced, actuators reconditioned.
Why customers choose us
- Anti-surge valve stroke time testing included — documented to <1s full stroke.
- Cv sizing verification for every valve against your actual operating conditions.
- Actuator rebuild kits available for immediate dispatch.
- Drop-in replacement — same flange pattern, same actuator interface.
Frequently asked questions
Can you refurbish my existing valves?+
Yes. We strip, inspect, re-seat, re-seal, and actuator-rebuild all major centrifugal compressor valve types. Typical turnaround is 2–4 weeks.
How do I know if my anti-surge valve is properly sized?+
Send us your compressor performance map and operating conditions — we'll verify the Cv and recommend resizing if the current valve is marginal.
Do you supply valve actuator rebuild kits?+
Yes — diaphragm kits, spring kits, positioner rebuild kits for Fisher, Valvtechnologies, Dresser, and other major valve brands.
What brands do you support?+
We supply and refurbish valves originally fitted to Cameron, Ingersoll Rand, Atlas Copco, Centac, and most other centrifugal compressor OEMs.
