Park Control Valve
Bendix

Parking control valve style unit designed to manage tractor and trailer parking brake signals and sequences. The porting arrangement enables flexible routing across typical tractor and trailer configurations, including a 3/8 PTC exhaust and multiple supply and delivery ports sized to 3/8 PTC threads. With a tractor trip pressure range of 30 to 40 psi and a broad operating window from -40 to 200 F, the assembly supports reliable operation across cold starts and hot climates. A mounting footprint of 136.14 mm width, 91.95 mm height, and 131.32 mm length, together with a 10-24 UNC-2B mounting thread, provides a compact yet sturdy installation. Buttons included add manual override or service functions in certain installations, improving diagnostics and servicing. VMRS 013-010-017 places reference in the valve family related to parking and tractor sequencing, while category 41532 identifies its role in parking and control system components. This part is critical for safe immobilization during maintenance or on grades, ensuring predictable release when commanded and compatibility with standard Bendix style control networks.
