Hydraulic & Pneumatic Controls repair
Proportional and servo valves, valve amplifiers, actuators and compressor controls. Proportional and servo valves, their amplifier cards and actuator controls link electronics to hydraulics. Faults can sit in the valve's coil or electronics, the amplifier card or the hydraulics, and each is checked separately.

Common faults
What usually fails on Hydraulic & Pneumatic Controls
Amplifier card faults
Failed output stages or supplies on valve amplifier cards cause no movement or full-on valves.
On-board valve electronics
Integrated electronics fail through heat, vibration or supply surges.
Coil failures
Open or shorted solenoid coils.
Contamination
Dirty oil causes sticking spools and erratic control, which can look like an electronics fault.
Feedback sensor faults
Spool position and pressure feedback sensors giving wrong signals.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Check the command signal and supply to the valve or card.
- Check oil condition and filters.
- Note whether movement is absent, erratic or stuck at one end.
Leave to a specialist
- Valve electronics and amplifier repair.
- Setting gain, offset and ramps.
- Work on pressurised hydraulics.
Warranty. Repairs carry a warranty of 30 days to 6 months, depending on the item and the repair; the exact term is confirmed before work starts.
FAQ
Hydraulic & Pneumatic Controls repair questions
Does the valve need to be sent with the hydraulic control?+
For an amplifier card, not necessarily; it can be tested on a load. Send the valve too if it has integrated electronics or the fault might be in its coil or feedback.
