On reciprocating compressors, valves are critical to guarantee performance and reliability. On steam turbines, they control performance and safety. On turbo-machinery compressors, non-return, blow-off and recirculating valves impact safety and efficiency. Guide vanes are critical for blowers and expansion turbines. Many of these valves and vanes are actuated. We therefore supply, inspect and overhaul a high number of valves and actuators.
