Land Rover Part Number: RVH000046 - Transfer Relief Valve - Suspension
RVH000046 is a transfer relief valve fitted to the reservoir tank of the air suspension system. Three air pressure relief valves are fitted per vehicle; the other two relief valves are RVH000055 for the rear axle and RVH000095 for the front axle. The valve protects the reservoir and downstream pneumatic components by opening at a calibrated pressure to release excess air and by remaining closed to preserve system pressure when required. Use the compatibility data below to confirm fitment against your V.I.N.

- Discovery 3 (2005-2009) - To VIN 9A999999
- Discovery 4 (2010-2016) - From VIN AA000001

Frequently Asked Questions
RVH000046 controls excess air pressure in the suspension reservoir by opening at a set pressure to release surplus air, protecting lines, distribution valves and other pneumatic components from over-pressurisation. It operates as part of the air supply circuit alongside the compressor and corner distribution valves to maintain reservoir pressure required for ride-height and damping control. A valve that sticks closed can allow reservoir pressure to rise above the calibrated limit; a leaking valve can permit unwanted pressure loss and affect suspension height response.
