Fitment & Compatibility
：
WG9925550711 Electric Directional Valve is designed for Sinotruk HOWO and SITRAK heavy-duty trucks, primarily used for dual-tank fuel switching and hydraulic control in lifting and steering systems. With fast response and stable performance under various operating conditions, this valve is manufactured to OEM specifications as a direct-fit replacement. It is compatible with a wide range of models including HOWO T7H, TX, SITRAK C7H, C9H and other comparable heavy-duty vehicles. For fitment verification, simply provide your truck model or VIN and we will assist with confirmation.
Material & Performance：
The valve body is made from high-strength die-cast alloy, tough enough to handle constant pressure and vibration.
Inside parts like the spool and seals use wear-resistant metal and oil-resistant rubber, so it seals well, doesn't age easily, and works reliably in both hot and cold temperatures.
The magnetic coil reacts quickly without using too much power.
Oil passages are precisely machined for smooth flow and low pressure loss. Even with frequent use under high pressure, it doesn't jam or leak easily.
Production & Quality Inspection ：
This valve goes through precision machining, assembly, sealing checks and aging tests during production.
We keep tight quality control at every step.
Every unit is fully tested before shipping - pressure test, leakage check, and response performance.
Only parts that pass all tests are shipped. Each valve is marked with a batch code for full traceability.
Service Life & Practical Value& MOQ ：
With normal use and maintenance, this electric directional valve holds up well over time, even in tough long-haul, construction and mining conditions.
A worn or faulty valve can lead to failed fuel switching, weak hydraulic pressure or slow lifting.
Replacing it with this reliable part restores normal function, cuts down on downtime and prevents unexpected breakdowns.
