About governor valve repair kits
The governor controls when the compressor loads and unloads, keeping system pressure between its cut-in and cut-out settings.
When to replace
Pressure that climbs too high, a compressor that never unloads, or rapid cycling are symptoms of a worn governor.
What's in the kit
Governor kits include seals, O-rings, valves and springs to restore accurate cut-in and cut-out pressures. All 2 governor valves lines are manufactured by Pitchline Engineering in an ISO 9001 environment in Pinetown and supplied from our Pinetown branch across South Africa.
Governor Valves questions
What does a truck air governor do?
It signals the compressor to stop pumping at cut-out pressure and start again at cut-in pressure.
Why does my air pressure keep rising past normal?
A sticking governor that never signals unload is a typical cause, along with unloader faults.
Do you supply unloader valve kits too?
Yes. See the Unloader Valves category.
