About load sensing valve repair kits
Load sensing valves adjust braking force to the axle load, preventing wheel lock on an empty vehicle and giving full braking when loaded.
When to replace
Wheels locking when empty, weak braking when loaded or air leaking at the valve point to worn internals or seized linkage.
What's in the kit
Load sensing valve kits include diaphragms, seals and valves to restore correct proportioning. All 7 load sensing valves lines are manufactured by Pitchline Engineering in an ISO 9001 environment in Pinetown and supplied from our Pinetown branch across South Africa.
Load Sensing Valves questions
What does a load sensing valve do on a truck?
It varies air pressure to the brakes based on axle load so braking suits whether the vehicle is empty or laden.
Why do my rear wheels lock when the truck is empty?
A faulty or mis-set load sensing valve can over-brake the axle; a rebuild and adjustment is needed.
How many load sensing valve kits are in the range?
