About relay valve repair kits
Relay valves and modulators apply and release the brakes quickly using air from a nearby reservoir, controlled by a small signal from the foot valve.
When to replace
Delayed application, air leaking at the exhaust or uneven axle braking indicate worn relay valve seals and pistons.
What's in the kit
Relay control valve kits include inlet/exhaust valves, piston seals and O-rings, including modulator kits. All 37 relay control valves lines are manufactured by Pitchline Engineering in an ISO 9001 environment in Pinetown and supplied from our Pinetown branch across South Africa.
Relay Control Valves questions
What does a relay valve do in an air brake system?
It uses a control signal to deliver reservoir air rapidly to the brake chambers, speeding up application and release.
Why does my relay valve leak when the brakes are applied?
A worn inlet/exhaust valve or piston seal; a relay valve repair kit replaces them.
Does ManuMark supply ABS modulator kits?
Modulator kits are included in this category where listed.
