Product Description
WG9000360520 Air Suspension Height Control Valve is a key component of the SINOTRUK HOWO air suspension system. Its primary function is to regulate the air flow in and out of the air springs, ensuring the vehicle maintains a stable and correct ride height under different load conditions.Whether the truck is empty, partially loaded, or fully loaded, this valve automatically adjusts the suspension level to keep the chassis balanced, improve ride comfort, enhance handling stability, and reduce tire wear.
Manufactured with a high-precision aluminum alloy valve body, the unit offers excellent corrosion resistance, durability, and airtight performance. The upgraded valve core and sealing system provide fast response and accurate air control, reducing airbag stress and extending suspension lifespan.
Designed according to SINOTRUK OE specifications, WG9000360520 ensures perfect compatibility and plug-and-play installation for HOWO, HOWO A7, and other air-suspension-equipped models. It is an ideal replacement part for workshops, fleet maintenance, and aftermarket distributors.
