- Manufacturer: Moog Inc.
- Series / Models: Series 60 (e.g., Moog 60-xxx, Type 60)
- Device Type: Two-Stage Nozzle-Flapper Industrial Hydraulic Servo Valve
Moog Series 60 hydraulic servo valves are legendary precision flow control devices designed for demanding industrial applications, including hydraulic presses, injection molding machines, metal rolling mills, and turbine positioning actuators.
Due to decades of continuous service and exposure to particulate oil contamination, these legacy valves suffer from clogged pilot nozzles, mechanical spool-and-sleeve wear, armature binding, or coil insulation breakdown. Typical symptoms include severe null drift, high internal leakage, sluggish step response, or total failure to respond to input current signals.
What we service on Moog Series 60 servo valves:
-
Coils: Testing, rewinding or replacement of damaged electrical coils, permanent magnet re-magnetization, and flexure tube replacement.
-
Pilot Stage (Nozzle-Flapper): Ultrasonic micro-cleaning of pilot nozzles, flapper alignment, and pilot stage flow adjustment.
Benefits of our repair service:
-
Avoid Expensive System Retrofits: Servicing legacy Series 60 valves eliminates the need to redesign hydraulic manifold blocks or replace electrical drive amplifiers for modern valve lines.
-
Restored Factory Performance: Complete mechanical overhaul restores original flow gain, tight null characteristics, and rapid frequency response.
