Description
Quality replacement cab height and leveling control valve with dump function, a direct bolt-in for WABCO 4640070040. Supplied with the 200 mm lever arm and push-in air fittings. OTR is a FleetPride house brand; this version uses ceramic friction surfaces in place of aluminum.
Signs You Need a New Height Control Valve
- Cab sags or settles overnight and will not re-level
- Cab rides too high or too low and will not adjust – valve stuck open or closed
- Continuous air leak or hiss from the exhaust port
- Cab oscillates or hunts up and down at road speed
- Slow leveling response after a load or ride height change
- Leaking at the push-to-connect ports
- Seized or corroded lever pivot after winter salt exposure
- Air compressor cycling excessively
