Original OE Number: RVH500070, RVH000046, RVH000045

Product Name: Land Rover Air Suspension Distribution Valve, Air Suspension Solenoid Valve Block Assembly, Air Suspension Pressure Control Valve, Air Suspension System Air Pressure Shunt Valve

Installation Position: Middle section of chassis air‑suspension pipeline, between air compressor and air spring lines. Universal for whole vehicle, no front/rear/left/right distinction. It is the core pressure‑stabilizing control valve for Land Rover L322, L320, LR3, LR4 chassis air suspension system.

Product Description

RVH500070 / RVH000046 / RVH000045 is OEM‑grade dedicated air suspension distribution valve for classic older Land‑Rover models. Precisely fits Range‑Rover L322, Range‑Rover Sport L320, Discovery 3, Discovery 4 high‑spec versions with factory air suspension. Acting as the air‑pressure control core of Land‑Rover air suspension system, it realizes four‑wheel independent air‑pressure distribution, system pressure stabilization & retention, intelligent body‑height adjustment and automatic pipeline pressure balance. It manages inflation, pressure‑holding and pressure‑relief logic for four air springs, keeps consistent body level, stabilizes chassis height and prevents air‑pressure imbalance, serving as the core valve component for reliable air‑suspension operation.

Original distribution valve fitted on L322 / L320 / LR3 / LR4 works under severe chassis conditions: muddy‑wet environment, sharp temperature fluctuation and frequent high‑pressure cycling. With aging mileage, common failures occur: solenoid sticking, carbon‑deposit jam, hardened aged rubber seals, micro air leakage, poor pressure retention and unbalanced four‑wheel air pressure. Typical vehicle symptoms: one‑side or full‑vehicle body sagging after overnight parking, left‑right height offset, non‑stop compressor cycling, slow or jerky lifting, body tilt‑shake while driving, dashboard air‑suspension warning lamp, fault codes for pressure leakage, abnormal pressure‑holding and height calibration error.

This Land‑Rover dedicated distribution valve is 1:1 precisely reproduced against OEM data of RVH500070, RVH000046, RVH000045. Valve‑runner aperture, solenoid switching frequency, high‑pressure resistance rating, ECU signal parameters, port dimensions and plug‑pin definitions fully comply with OEM standards. It adopts high‑strength precision aluminum‑alloy valve body, high‑low‑temperature resistant high‑pressure fluororubber seal kit and anti‑interference rust‑proof electronic valve‑core. Features: fast response, accurate shunting, stable pressure‑holding, anti‑aging, corrosion‑resistance and zero‑leakage under long‑term high‑pressure load. Non‑destructive direct in‑situ replacement, no rewiring, no drilling and no programming required, perfectly compatible with original Land‑Rover air‑suspension ECU. It thoroughly fixes common defects of Discovery3 / Discovery4 / Range‑Rover L322 / Range‑Rover Sport L320: body sagging, air leakage, body tilting, height imbalance, overworked compressor and abnormal lifting, with ultra‑low rework rate. It is a hot‑sale spare part for vehicle repair, parts wholesale and cross‑border export.

Interchange Remark: Above part‑numbers are OEM upgraded iterative replacements. RVH000046 / RVH000045 are updated successors replacing old RVH500070. Valve‑runner structure, pressure‑resistance parameters, ECU signals, mounting interfaces and sealing specifications are 100 % identical. They are fully interchangeable distribution‑valve assemblies supporting direct non‑destructive swap‑in without modification or programming, zero compatibility faults.

Q1: Are RVH500070, RVH000046 and RVH000045 fully interchangeable?

A: Yes, fully interchangeable. They are batch‑upgrade part‑numbers for the same OEM valve; structure, dimension, ECU and pressure‑resistance parameters are identical and can be swapped arbitrarily.

Q2: Does this distribution valve have dedicated front/rear/left/right positions?

A: No position limitation. Universal for all L322 / L320 / LR3 / LR4 air‑suspension vehicles, simple stocking and wide compatibility range.

Q3: Can it be installed on low‑trim mechanical‑suspension Land‑Rover?

A: No. This part is exclusively for high‑spec vehicles with factory‑fitted air suspension. Mechanical‑chassis vehicles have no matching air‑suspension pipelines, control modules or ECU logics and cannot be fitted.

Q4: Does it fit new‑generation Range‑Rover / Discovery 5?

A: Not compatible. This valve is designed for 2002‑2013 old‑style Land‑Rover. New‑generation chassis features completely different valve‑structure, ECU programming and pipeline layout and cannot be mixed‑fitted.

Q5: Is programming required after replacing the distribution valve?

A: No coding or programming required. After in‑situ replacement, evacuate pipeline air, perform air‑tightness test, clear fault codes and calibrate body height, then vehicle ECU will recognize and adapt automatically.

Q6: What faults on old Land‑Rover require distribution‑valve replacement?

A: Replacement is recommended for static body sagging, single‑side drop, serious left‑right height imbalance, non‑stop compressor operation, slow/jerky lifting, air‑suspension warning lamp, system pressure‑relief / pressure‑holding faults and body‑tilt‑shake in off‑road driving. These symptoms are mainly caused by valve‑core sticking and seal aging, which can be fully solved by fitting a brand‑new assembly.
