New Condition SHACMAN Delong Truck Seat Intake Valve with Height Adjustment Control Truck Parts for X3000 (OE:1440367)

This brand-new intake valve, engineered specifically for SHACMAN Delong X3000 truck seats with OE reference 1440367, serves as a critical component in regulating seat height through precise air intake control, blending reliability with tailored adjustability for heavy-duty applications.

At its core is a height adjustment mechanism that modulates compressed air flow into the seat’s pneumatic lift system, enabling smooth, incremental height changes (typically 10–15cm) to suit drivers of varying statures. A responsive valve core ensures accurate air intake regulation, preventing over-inflation or sudden deflation—key for maintaining stable seating positions, even on bumpy roads. This precision eliminates the "sagging" or "jerky movement" common with worn valves, letting drivers lock in their ideal height with confidence.

Constructed for durability, the valve features a corrosion-resistant zinc-plated housing, built to withstand extreme temperatures (-30°C to 70°C), vibration, and exposure to road debris, oil, or moisture. Its internal seals, made from high-grade nitrile rubber, ensure airtight performance, resisting degradation from air contaminants and extending service life beyond 80,000+ adjustment cycles.

As a direct OE replacement, it fits seamlessly into SHACMAN Delong X3000 seat assemblies, aligning with factory mounting points and pneumatic lines without modifications. This plug-and-play design simplifies installation, reducing truck downtime for fleet maintenance.

For drivers, the benefits are clear: customizable height enhances ergonomics, ensuring proper alignment with pedals and controls to reduce back and leg strain during long shifts. For fleets, its new-condition build and OE compliance guarantee consistent performance, lowering repair needs and preserving seat longevity.

Rigorously tested for air tightness (up to 10 bar pressure) and durability under cyclic use, this intake valve meets SHACMAN’s strict standards, making it an essential part for keeping X3000 truck seats functional, comfortable, and reliable.
