SW New Condition ISRI NTS6860 870 Double Valve Seat Switch Truck Parts

The New Double Valve Switch, a specialized seat valve designed for ISRI NTS6860/870 SW25 truck seats, serves as a critical pneumatic control hub, enabling precise regulation of dual seating functions to enhance driver comfort and operational efficiency in commercial vehicles.

Engineered exclusively for these ISRI models, this valve integrates two independent yet synchronized valves, streamlining the management of key seat adjustments—such as height and tilt, or lumbar support and cushion firmness—through a single, intuitive component.

At its core, the double valve design allows simultaneous or separate control of two pneumatic circuits within the seat. For instance, it can modulate air flow to both the height-adjustment bladders and the tilt cylinders, enabling drivers to adjust seating position and angle in harmony, or prioritize one function without disrupting the other.

This dual functionality eliminates the need for multiple standalone valves, reducing complexity in the seat’s pneumatic system and ensuring smoother, more coordinated adjustments. The switch responds swiftly to driver input, with precise pressure modulation that prevents abrupt movements, a critical feature for maintaining stability during adjustments.

Constructed as a new-condition part, the valve arrives free from wear, corrosion, or internal degradation, guaranteeing uncompromised performance. Its housing is crafted from high-strength, corrosion-resistant metal alloys or reinforced polymers, built to withstand the vibration, temperature fluctuations, and moisture common in truck cabs.

Internal components—including valve diaphragms, seals, and actuators—feature durable materials that resist fatigue from repeated use, ensuring airtight operation and preventing leaks that could degrade adjustment precision over time.

Tailored for ISRI NTS6860/870 SW25 seats, this valve is engineered to meet OE specifications, ensuring seamless compatibility with the seat’s existing pneumatic lines and control mechanisms.

It fits precisely into factory mounting points, with pre-drilled ports that align with air hoses, simplifying installation and eliminating the need for modifications. This direct-fit design ensures that the seat retains its original adjustment range and responsiveness, restoring full functionality to worn or malfunctioning valve systems.

For drivers, the double valve switch enhances control by consolidating dual adjustments into a streamlined interface, reducing the need for frequent toggling between controls and minimizing distraction.

For fleet managers, its new-condition reliability translates to fewer breakdowns, lower maintenance costs, and extended service life for seat pneumatic systems.

As a dedicated component for ISRI NTS6860/870 SW25 seats, this Double Valve Switch is more than a replacement part—it’s a guarantee of coordinated, precise seating control.

By merging dual functionality with robust design, it ensures every adjustment in ISRI trucks feels intentional, comfortable, and built to last.
