Air Pressure Limiter Valve: Description and Operation

Pressure-Holding Valve

The pressure-holding valve is maintenance-free and may only be replaced in the case of a noticeable leak.

The vehicle must be on a lifting platform to replace the pressure-holding valve. The vehicle wheels must rotate freely.

• The pressure-holding valve is open when the air line is screwed into the air spring shock absorber.

• If the air line is disconnected from the air spring shock absorber, the pressure-holding valve is closed.
