HydroCOM Actuator Workshop testingAfter assembly

Valve housing:2 hour leakage test at 150 bar

Valve housing:High pressure dynamic test at 8000N:Criteria: 10mm travel of high pressure piston must take at least 4s

Electric function test of complete actuator

8000N


Spare Actuator Adoption

Following parts must be in accordance with the partlist for the compressor and actuator the spare actuator is intended to be used:

- Solex Nozzle (diameter)- Soft touch damper: length of throttle piston- Seal housing design / sealing materials- Is integrated oil pressure sensor required?- Correct bus address- Termination yes/no

(must be set for last actuator on the bus)
