 Product Description

· VU4 valve block function

Air suspension solenoid valves are electronic valves that open and close to fill or vent each airbag. A single valve will control each corner of your air suspension system. The valves are integrated into a valve manifold and are installed between the compressor and the airbags.

· VU4 valve block work principle

These " gates " allow air to flow from your air tank to your airbags through the airline. Our valves are normally closed, and air can't pass through until the valve is activated with 12-volt power from your toggle switch, controller, or switch box.

Air Suspension Control Valves automatically control the vehicle's ride height by inflating and deflating the air suspension bellows to adjust for variations between loaded and unloaded vehicles.

· VU4 valve block reason for stopping work

Over time its O-rings can dry rot, causing damage to the compressor via air leaks and overworking, along with moisture damage to the electrical solenoid components.
