WG9000360523 M22*1.5 Sinotruk Howo A7 SITRAK C7H
Man Truck 4 Four Circuit protection Valve
The Four-Circuit Protection Valve (OEM WG9000360523) is a vital safety component in the air brake system of heavy-duty trucks, including SINOTRUK HOWO A7, SITRAK C7H, and MAN models. Its primary function is to distribute compressed air to four independent brake circuits while protecting each circuit from pressure loss in the event of a failure—ensuring continuous braking capability and maximum driving safety.
Engineered with precision valve control and a robust, corrosion-resistant housing, this M22×1.5 protection valve maintains stable system pressure even in extreme working conditions. It prevents total air system failure by isolating damaged circuits and prioritizing critical braking functions.
Designed to meet strict OEM standards, it offers perfect compatibility, quick installation, and long service life, making it an essential part for maintenance, safety upgrades, and air system repairs in commercial fleets.
