Product Overview
The WG9719360005 foot brake mastervalve is an original high-quality pneumaticbrake part for SINOTRUK heavy-duty trucksIt serves as the core control component ofthe vehicle’s air brake system. Adopting areliable dual-circuit braking structure, thisbrake valve provides sensitive, stable, andlinear braking performance duringlong-distance transportation, mountainclimbing, and heavy-load driving. It
effectively solves common failures such asweak braking, slow response, air leakage,and pressure loss
Compatible Vehicles
Perfectly fits SINOTRUK HOWO T7H, T5GTX, MAX, SITRAK C7H, G7, and HOHANN5G/N7G series trucks. It is a directreplacement for the original OEM part withfully matched installation holes and air pipeintertaces.
Key Features
1. Dual-circuit safety design
Dual independent air circuits ensure saferdriving. If one circuit fails, the other circuitstill works normally to avoid total brakefailure.
2Sensitive and linear braking
Precision internal spring and valve corestructure deliver smooth braking
feedback, preventing sudden braking andreducing tire and brake pad wear.
3. Excellent airtight performanceAdopts high-quality wear-resistant andaging-resistant rubber sealingcomponents. Strict internal grindingprocess effectively prevents air leakageand pressure drop under long-term
vibration and high-load working
conditions.
4. Durable aluminum alloy bodyIntegrally die-cast aluminum housingfeatures high strength, shock resistance,corrosion resistanc and long service life,adapting to comp.oad conditions.
5. Direct OEM replacement
Fully consistent with original installationsize, hole distance, and interface
standard. No modification required for
quick and easy installation.
Common Replacement Symptoms
Weak braking and longer stopping
distance
· Air leakage from the brake valve
· Slow brake response and soft brake pedal
Unstable braking force during driving
