Relay Valve
Bendix

Relay valve assemblies are central to multi-circuit air brake systems, distributing compressed air from the primary supply to eight separate delivery ports while maintaining controlled exhaust and balanced porting. This unit features a 117.30 mm wide and 109.20 mm tall body with 3/8-16 UNC-2B mounting threads and a 90 degree control port arrangement for flexible line routing. The balance port and control port thread sizes are specified to accommodate standard fittings, while the supply port and eight delivery ports use 1/2-14 NPT type connections to support robust air flow. The exhaust port is equipped with a dust shield to extend service life in dirty environments, and the unit accepts a wide operating temperature range up to 200 Deg F and down to -40 Deg F, making it suitable for a broad spectrum of climates. Crack pressure is rated at 5.50 psi, ensuring timely and predictable actuation of secondary circuits during braking events. This component is a critical junction in the brake system, enabling coordinated application of multiple brakes and improving vehicle stability, control, and safety in diverse operating conditions.
