Tyre pressure control valve 131-4222010-B ZIL-131, aftermarket

Tyre pressure control valve 131-4222010-B is an aftermarket part for the ZIL-131, Ural and KrAZ trucks.

The tyre pressure control valve is used on off-road trucks with central tyre inflation (such as the ZIL-131, Ural and KrAZ) to change tyre pressure from the cab. With the valve handle the driver inflates the tyres, deflates them or sets the system to neutral, lowering the pressure on soft ground for traction and restoring normal pressure on hard roads. A leaking valve lets the tyres go down by themselves, and a sticking one prevents pressure adjustment.

Fitting

Fit the valve in its place in the cab panel and connect it to the air lines in the same order as the old one. Release the air from the system before the change. After fitting, try every valve position, watch the tyre pressure gauge during inflation and deflation and check the joints for leaks with soapy water. Also check the wheel valves and rotary joint seals of the system for leaks.
