Specifications
The Automann 170.065145 is a BPR1-type proportioning (relay) valve engineered for robust performance in heavy-duty air brake systems. It features a 4 PSI “crack” (actuation) threshold, multiple delivery ports (typically 3/8" FPT), a 1/8" control port, and a 1/2" supply port. As a bobtail proportioning valve, it helps reduce rear brake pressure when no trailer is connected, providing safer, balanced braking. The unit is built to match OE specifications, offering a direct alternative to Bendix 065145 / 65145N and related equivalents. Its durable design withstands the rigors of commercial use, delivering consistent modulation through repeated cycles. Whether for preventive maintenance or repair, this proportioning valve is a dependable component for medium- and heavy-duty trucks that rely on controlled brake modulation during unloaded or partial-load runs.
