Compressor Assembly Valve Block - Operation

OPERATION

WARNING:
All pressurized air suspension components contain high pressure air (up to 220 psig). Use extreme caution when inspecting for leaks. Wear safety goggles and adequate protective clothing when inspecting or servicing the air suspension system. A sudden release of air under this amount of pressure can cause possible serious or fatal injury.

WARNING:
Support the vehicle by supplemental means before performing any work on the air suspension system to prevent the vehicle from changing height. Before any given component is to be serviced it must be deflated. Servicing the air suspension system without supplemental support, or with pressure in the specific component, can cause possible serious or fatal injury.

The valve block mechanically controls the flow of air in the system and maintains the pressure in the reservoir, and in each air spring individually. Valves and solenoids in the valve body open and close to increase or reduce pressure to air lines that connect to each pressurized component allowing the system to move each corner of the vehicle up or down as necessary. All wiring connected to the valve block is directly from the Air Suspension Control Module (ASCM) which fully controls the valve body. The ASCM determines pressure from an internal pressure sensor in the valve body.
