SINOTRUK Truck Transmission System / Pneumatic Gear Shift Control System Parts Pneumatic Lock Valve Assembly WG2203250010
The WG2203250010 Pneumatic Lock Valve Assembly is the lock valve in the SINOTRUK HOWO transmission's pneumatic circuit, running on compressed air to control the interlock for the range-shift mechanism — once the main gearbox is in gear, it shuts off the air passage to the range section so the range box can't be shifted at the wrong moment, which protects the range-section synchronizer from a mistimed range change. It sits in the transmission air pipe and valve assembly, listed in the parts book alongside the WG2203250003 Double H valve, air fittings, springs, bushings, O-rings, and gaskets, and it is strictly a transmission air-circuit part — not a brake valve and not a cab air valve. On multi-speed boxes like the HW15710, it works with the shift circuit to keep the main gearbox and the range section in step. When you replace it, check the whole circuit at the same time — air lines, fittings, O-rings, gaskets, and the Double H valve — because a leak or a restricted line anywhere in the circuit throws the same symptoms as a failed lock valve, so swapping the valve alone won't always clear the fault. This part fits transmission overhauls, pneumatic shift-system repairs, and lock valve replacement on compatible SINOTRUK HOWO trucks.
