WG9000360523 M22*1.5 Sinotruk Howo A7 SITRAK C7H Man Truck 4 Four Circuit protection Valve  

Product Description

The WG9000360523 Four-Circuit Protection Valve (M22×1.5) is a high-quality OEM replacement pneumatic safety valve designed for SINOTRUK HOWO A7 and SITRAK C7H MAN heavy-duty trucks. This valve is a critical component of the air brake system, responsible for distributing compressed air into four independent circuits while protecting each circuit from pressure loss or failure in the others.

By isolating air circuits, the valve ensures that a malfunction in one circuit does not compromise the entire braking system, significantly improving vehicle safety, braking reliability, and system stability. Manufactured to OEM specifications, the WG9000360523 features precise internal control, durable sealing, and stable pressure response under heavy-load and long-distance operating conditions.

This four-circuit protection valve is ideal for brake system repair, replacement, and fleet maintenance, ensuring consistent air pressure control and long service life.
