The front and rear valve blocks are identical in design. They regulate the air supply and distribution between the front or rear air shock absorbers. The difference between the two valves is in the connections from the valve blocks to the left and right air shock absorbers, as well as the size of the valves. The valve block must be installed on the correct axle. Installing the wrong valve block will not cause the air suspension system to fail, but will cause slow lift and release, and uneven lift and lowering of the front and rear axles.
The front valve block is secured to the right side of the front bumper assembly mount. The valve block has three mounting brackets, under which rubber vibration-insulating supports are installed. The rubber supports are installed in the bumper mounting grooves. The valve bracket is inserted into the holes above the slots and is pulled down into its seat in the slots.
The rear valve block is located at the front of the left rear suspension head. The valve block has three mounting brackets with rubber vibration-isolating mounts that are installed in the bracket with three slots. The bracket is attached to the left side of the chassis. The vibration-isolating rubber mounts are located in V-shaped slots and are pulled down into their seat in the slots.
The front and rear valve blocks have three connecting pneumatic pipes with Voss-type nipples. One connection is intended for air inlet/outlet into the receiver valve block. The other two connections are intended for creating pressure in the left and right elastic pneumatic elements.
Each valve block contains three solenoids: two shock absorber valves and one bypass valve. The air suspension control unit controls each solenoid valve individually. The solenoids have a resistance of 2 ohms at 20°C (68°F).
Shock absorber valves
Shock absorber valves regulate the intake and exhaust of air to individual pneumatic springs. When the electromagnet is not energized, an internal spring holds the shock absorber valve closed. When current flows through the electromagnet, the valve opens and air can flow into or out of the pneumatic spring.
Bypass valves
The bypass valve connects two air springs mounted on the same axle. When no current flows through the solenoid of the bypass valve, air cannot pass from one air spring to the other. When current flows through the solenoid, the valve spool moves and air can pass from one air spring to the other. This increases wheel mobility and improves comfort when driving at low speeds.
