Le WG9000360507 Check Valve is a cornerstone of the Sinotruk howo parts ecosystem, designed to safeguard your vehicle’s pneumatic circuits against dangerous backflow.
Whether you are operating a HOWO 371 or a newer T7H model, this check valve (also known as a non-return valve) ensures that compressed air moves in a single direction—maintaining the pressure required for consistent braking and air suspension performance. Manufactured from high-strength alloy and fitted with heat-resistant internal seals, the WG9000360507 is built to withstand the carbon buildup and oil vapor common in high-mileage heavy trucks.

To maintain the long-term reliability of your Sinotruk howo parts, our engineering team recommends the following when replacing the WG9000360507:
-
Directional Flow Awareness: Look for the cast-in arrow on the valve body. This indicates the direction of airflow. Installing it in reverse will completely block the air supply to the tanks, leading to brake failure.
-
Clean the Lines: Before threading in the new valve, inspect the air lines for carbon deposits or moisture. A clogged line can cause the internal spring of the new valve to stick prematurely.
-
Avoid Over-Taping: While thread sealant or PTFE tape is recommended, do not apply it to the first two threads. Excess tape can break off, enter the pneumatic system, and clog downstream valves.
-
Leak Testing: Once installed, charge the system to full pressure and perform a "soap bubble test" on the joints. Even a microscopic leak can cause the air compressor to overwork, leading to premature failure of other Sinotruk howo parts.
-
Torque Settings: Use a calibrated wrench to tighten to 35-45 Nm. Excessive torque may crack the alloy housing.
