Products Description
The WG97197100042 is a wheel solenoid valve for HOWO T7H/TH7/A7 trucks-core control part of the wheel brake system. It controls brake pressure on/off for reliable braking and release. We've sold it to 30+ repair shops and fleets for 5 years-users say it's steady: no leakage, no valve failure, no noise, no voltage damage.
It has brass valve body (high-pressure resistant), stainless steel valve core (wear-resistant), and nitrile rubber seal (high-temperature resistant). Internal coil is flame-retardant, valve body is anti-oxidation plated. Vibration, -30℃ to 120℃, ≤1.6MPa pressure, rain, dust, oil-none mess it up. Receives control signals to open/close quickly, regulates pressure for stable braking. Fits HOWO T7H/TH7/A7's original pipeline and bracket perfect: remove old valve, install direct, no mods. We test pressure resistance, response speed, service life, so it's reliable.
Features And Advantages
① Precise & fast: ≤0.2s response, accurate pressure control, no braking delay.
② High-pressure & leak-proof: Brass body bears ≤1.6MPa; rubber seal fits tightly, no leakage.
③ Durable & stable: Stainless steel core resists wear; coil avoids burnout; plated body resists rust, lasts ≥4 years.
④ Fits HOWO fast: Interface, mounts, wiring match original. Connect pipeline/wiring, fasten bolts-easy install.
Application Scope
Only HOWO T7H/TH7/A7 (wheel solenoid valve). No old HOWO 7, SHACMAN, Dongfeng-different brake specs, causes safety risks.
