The Bendix 802914 R-14 Relay Valve is a heavy-duty air brake control valve designed to improve brake response by delivering reservoir air directly to the service brake chambers when signaled by the treadle (foot) valve. The R-14 design is commonly used on tractors, trucks, buses, and vocational vehicles equipped with air brake systems, providing fast, graduated brake application and release for consistent braking performance.
