This compressor valve plate is a critical component within the air brake system, regulating the flow of compressed air to and from the compressor. It ensures optimal pressure is maintained for reliable braking performance, unlike a worn plate which can lead to leaks and inefficient operation. Operators may notice a hissing sound from the air tanks, a spongy brake pedal feel, or the compressor running excessively without reaching cut-out pressure.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing valve plate often begins with a slight loss of air pressure or a faint hissing sound. If ignored, the compressor may struggle to build adequate air pressure, leading to intermittent braking issues and longer stopping distances. Continued operation with a faulty valve plate can overwork the compressor, potentially causing premature failure of the entire unit.
Ensure the compressor head is thoroughly cleaned of all old gasket material and debris before fitting the new valve plate. Avoid overtightening the compressor head bolts, as this can warp the plate or damage the threads.
Inspect the compressor head gasket and seals for signs of wear or leakage when replacing the valve plate.
