Automann 170.065476 R-12P Pilot Relay Valve | Replaces Bendix 065476

Automann 170.065476 R-12P Type Pilot Relay Valve

Restore precision control to your air brake system with this heavy-duty R-12P type pilot relay valve.

The Automann 170.065476 is a high-quality pilot relay valve designed to speed up the application and release of air pressure in your braking system. Specifically engineered for use in applications where a pilot signal is required to trigger the valve, the R-12P ensures that air reaches the chambers as quickly as possible, maintaining safe stopping distances for heavy-duty trucks and trailers.

Product Overview

As a critical component of the air brake system, the R-12P relay valve acts as a high-capacity remote-controlled air valve. It uses a low-volume air signal (the pilot) to control a large volume of air flow from the reservoir directly to the brake chambers. This Automann replacement is built to OEM specifications, offering a reliable, cost-effective alternative to Bendix and Freightliner original units.
