advantages

Heavy-Duty Steel Build for Long Service Life：we adopt premium SAE 1045 carbon steel for the valve body and forge it under high pressure, then go through full normalization treatment to release internal stress. This makes the valve body rigid enough to withstand 0.6-1.0MPa air pressure stably, with no deformation or cracking even in long-term heavy-duty operation.

Precision Machined Core for Instant Response：our CNC-machined copper alloy valve core ensures ultra-high concentricity. It perfectly matches the valve cavity, enabling the 24V solenoid to trigger air flow instantly with zero delay-delivering quick, crisp horn activation every time for heavy trucks.

Leak-Proof Sealing with Reliable Air Retention：the valve uses high-grade EPDM rubber sealing rings with a dual-lip design. Combined with one-piece injection-molded valve cavity, it eliminates seam gaps and tightens the fit completely, effectively preventing air leakage and maintaining stable system pressure in all working conditions.

OE Exact Fit for Quick, Hassle-Free Installation：we strictly follow the original dimension tolerance standard of WG9718710001 for CNC turning of all interfaces. The snap-on quick-connect design matches Howo's original air pipe and wiring port perfectly-direct replacement with no modification needed, cutting down maintenance time greatly.

FAQ

Q: Will this solenoid valve fit my Howo truck directly, with no extra modifications needed?

A: Absolutely. It's made to match the original OE specs exactly, so it's a straight drop-in fit for Howo A7, T5G, T7H, SHACMAN X3000 and FAW J6/J7. No wiring or piping tweaks required at all.

Q: My biggest headache with solenoid valves is air leaks-how's the sealing on this unit?

A: I totally get that concern. The WG9718710001 Howo Horn Solenoid Valve uses high-grade EPDM dual-lip seals paired with a one-piece machined valve body, zero seam gaps or weak joints. It holds 0.6-1.0MPa air pressure rock steady, and we never get leak-related returns on these units.

Q: How long should this solenoid valve last on our heavy-duty Howo fleets with daily long-haul runs?

A: The WG9718710001 Howo Horn Solenoid Valve easily hits over 300,000 km under normal heavy truck use. The forged steel valve body and precision copper core wear far better than generic aftermarket options, no premature jamming or electrical faults.

Q: Does it work seamlessly with the original 24V electrical system on our Howo trucks?

A: Yep, it's factory-tuned for the standard 24V heavy-duty commercial vehicle electrical system, max current ≤5A. It plugs right into your original wiring harness, delivers instant horn activation with zero lag, no electrical error codes at all.

Q: Do you offer any support if I need to confirm fitment with my truck's VIN?

A: We sure do. Just send over your truck's VIN, and our tech team can cross-check it against the valve's specs to confirm a perfect match-takes just a few minutes, no guesswork for your fleet maintenance.
