Adapted to other single-function pneumatic auxiliary devices, fully covering the key air path control needs of heavy trucks.

Its automated control features not only reduce the intensity of manual operation, but also improve control accuracy and response speed. degree, ensuring the coordinated operation of various pneumatic systems, indirectly improving the operating efficiency and driving safety of heavy trucks

Precision structure and quality advantages

Lightweight anti-corrosion structure: using black high-strength electromagnetic coils. + Aluminum alloy one-piece valve body combination design, the electromagnetic coil has strong insulation and excellent heat dissipation performance, and can withstand long-term high-frequency workloads; the aluminum alloy valve body greatly reduces its own weight while ensuring structural strength, adapting to the lightweight design requirements of heavy trucks, and with special anti-corrosion treatment, it can resist the erosion of rain, dust, acid and alkali corrosion and other complex road conditions, extending the service life of the product.

[P_STARTStable and reliable electrical connection: Equipped with a dual-pin electrical interface, the pins are made of highly conductive material, ensuring a tight fit during insertion and removal, strong connection stability, and effectively avoiding poor contact caused by bumps and vibrations; the interface has an anti-oxidation and anti-loosening design, adapting to the complex vibration environment of heavy trucks during long-term operation, ensuring stable circuit signal transmission.

Integrated and convenient installation: Adopting an integrated design, the electromagnetic control unit, air circuit interface, and other core components are integrated into one unit, significantly reducing the number of external pipeline connections and joints. This not only reduces air circuit resistance and leakage risk but also simplifies the installation process. No additional modification or complex debugging is required; it can be directly and accurately adapted to the original vehicle mounting position, improving maintenance and replacement efficiency.
