This WG9000360524 air brake relay valve is a high-quality replacement component designed for Sinotruk HOWO, Hohan and Sitrak series heavy trucks. As a key part of the pneumatic brake system, it quickly delivers high-pressure air to the rear wheel brake chambers, effectively reducing brake lag and ensuring sensitive, synchronous and stable braking performance.
Made of high-strength die-cast aluminum alloy body with imported high-temperature resistant rubber seals, it features excellent air tightness, stable pressure output, strong anti-vibration and anti-corrosion performance. The internal precision spool structure ensures smooth air flow and no air leakage during long-term heavy-duty operation.
All mounting holes, air port threads and interface dimensions are strictly manufactured in accordance with OEM standards, supporting direct bolt-on installation without any modification. It effectively solves common failures such as slow braking, asynchronous braking, air leakage and weak braking force.
With reliable quality and long service life, it is widely used in truck repair shops, logistics fleet maintenance and global heavy truck brake system parts wholesale. Stable stock and factory direct price make it an ideal choice for replacement.
