🚤 Trailer Compatibility & Application

• Suits compatible AL-KO iQ7 actuators

• Not for Hydrastar actuators

• Actuator diagnosis should confirm the dump valve is the cause before replacement

🔌 Function

Releases compressed air from the actuator pressure circuit so hydraulic brake pressure and the automatic park-brake function can disengage correctly.

Common signs of wear or replacement:

• Trailer brakes remain applied after reconnection

• Actuator will not vent or reset

• Air leaks continuously from the valve

• Valve flap sticks from contamination

• Compressor cycles repeatedly because pressure cannot be retained

• Inspect for water or debris in the pneumatic system

• Test park-brake application and release after replacement

• Have actuator faults diagnosed by a qualified technician
