MODEL 310: INLINE PULL CHAIN LANYARD AIR VALVE

CLASSIC MECHANICAL HORN ACTIVATION

Bring authentic, tactile control to your commercial or heavy-duty pneumatic setup with the premium Kleinn Model 310 Pull Chain Lanyard Air Valve. Explicitly engineered to interface with roof-mount air horn configurations, this mechanical inline valve bypasses electronic solenoid wiring entirely, allowing you to manually meter and unleash the full force of your air horns with a classic lanyard tug. Featuring a rugged construction, this heavy-duty valve delivers a zero-lag pneumatic response, providing an instantaneous, reliable blast every single time the chain is pulled.

VERSATILE INLINE COMPRESSION PLUMBING

The Model 310 is designed for a clean, inline install within your cabin's overhead plumbing run. Sized with standard 1/4" Outside Diameter (O.D.) compression tube fittings on both the inlet and outlet ports, it splices seamlessly between your onboard air tank feed line and the roof-mounted horn base. Engineered as a durable, non-locking spring-return mechanism, this manual valve returns instantly to the closed position the second the lanyard chain is released, protecting your air supply from accidental pressure drops.

Why Choose the Model 310 Lanyard Valve?

  • Authentic Mechanical Pull: Eliminates electrical relays, dashboard switches, and solenoid wires, delivering a traditional, manual big-rig train horn experience.
  • Dual 1/4" O.D. Compression Fittings: Features identical 1/4" O.D. compression tube ends for quick, reliable, and leak-free inline splicing into standard air lines.
  • Overhead Cab Optimization: Ideal for custom ceiling mount setups, providing drivers with an ergonomic hand-pull trigger layout.
  • Rugged Spring-Return Action: Heavy-duty internal spring snaps the valve shut immediately upon release, avoiding stuck open-flow scenarios.

THE VERDICT: The definitive mechanical valve for classic roof-mounted cabin setups. The Model 310 combines robust inline construction with simplified compression plumbing to ensure your roof horns trigger instantly with a simple, authoritative tug.

What's Included in the Box

  • Mechanical Valve: One (1) Model 310 inline hand pull lanyard valve assembly.
  • Pneumatic Ports: Two (2) integrated 1/4" O.D. high-pressure compression tube fittings (Inlet & Outlet).

🔴 PRO TIP: Ensure a perfect, leak-free seal on your overhead line run. When inserting your 1/4" O.D. high-pressure pneumatic tubing into the compression ports, ensure the hose ends are cut completely square and clean, and always apply a drop of premium liquid thread sealant like our genuine Kleinn JUICE to lock out slow phantom system leaks.
