Product Description

SINOTRUK HOWO Heavy Duty Truck WG2203250003 Transmission Gearbox Double H Valve


This Heavy Duty Truck Transmission Gearbox Double H Valve (Part No. WG2203250003) is a critical pneumatic control component engineered specifically for SINOTRUK HOWO manual transmission systems. By precisely distributing air pressure to the high and low-gear switching cylinders within the auxiliary gearbox, it eliminates sluggish gear conversions and prevents air leaks that cause range-shifting failures. Built to thrive in harsh fleet operating environments such as heavy logistics transport, mining worksites, and construction transits, this pneumatic valve ensures smooth, instantaneous range transitions, protecting internal synchronizer assemblies and maximizing mechanical uptime.

Product Specification

Part Number  WG2203250003

Quality Standard 100% Tested
Quality Certification ISO, CCC, GSO, CE, SGS, TUV
Weight 0.5 KG

Pneumatic Range Switching: Engineered to deliver instantaneous and precise air distribution, this pneumatic valve safely governs airflow to the auxiliary range cylinders. It ensures immediate high and low-gear range conversion under heavy cargo loads, completely removing pneumatic delay during critical slope climbs or heavy freight acceleration.
Hermetic Anti-Leak Integrity: Molded with premium internal sealing gaskets and a high-precision valve core cavity, this assembly maintains perfect airtightness under intense operational pressures. It completely mitigates common air pressure leaks at the exhaust port, protecting the transmission system from fluid contamination and localized vacuum drops.

Thermal and Dust Resistance: Featuring a rugged, hardened outer protective shell, this valve is structurally built to withstand intense thermal cycling and corrosive oil vapor exposure. It prevents fine mining dust and road salt crust from seizing the internal pilot pistons, enabling continuous, stable operation across desert hauls and mud-choked mining pits.

Direct OE Geometric Fit: Manufactured to exact factory-standard dimensional specifications, this valve provides an absolute 100% direct-fit replacement on standard heavy-duty truck gearboxes. Fleet mechanics can drop it straight into the existing pneumatic linkage block without any aftermarket modifications or custom routing adjustments, slashing maintenance labor hours.


Synchronized Shifting Smoothness: By neutralizing internal air-supply friction and maintaining constant air-line pressure feedback, this valve stabilizes shift actuation behaviors. It completely eliminates harsh gear clashing and annoying shifter vibration, bringing back a smooth, predictable, and secure driving feel to operators.

اشتريتُ قبل ثلاثة أسابيع حشوات زيت متينة لشاحنات أسطولي من شركة HOWO من هذا المتجر المستقل. بصفتي مدير أسطول أدير 22 شاحنة نقل بضائع في لاغوس، كنتُ بحاجة إلى حشوات مطاطية متينة تتحمل درجات الحرارة العالية على الطرق الأفريقية الوعرة. كل حشوة تناسب تمامًا دون أي تسريب للزيت أثناء النقل لمسافات طويلة. استغرقت الشحنة إلى ميناء لاغوس 8 أيام فقط، وكان فريق المبيعات سريع الاستجابة عندما طلبتُ أسعار الجملة.
