Bendix 803118 R-12 Relay Valve for Heavy Duty, HD Truck & Trailer. The relay valve in an air brake system functions as a relay station to speed up the application and release of the brakes. The valve is normally mounted at the rear of the vehicle in proximity to the chambers it serves. The valve operates as a remote controlled brake valve that delivers or releases air to the chambers in response to the control air delivered to it from the foot brake valve or other source. The R-12® and R-14® relay valves are designed for either reservoir or frame mounting.

Over the course of its history, Bendix has pioneered and revolutionized airbrakes and has been dedicated to furthering development of braking technology. Bendix was first established by Vincent Bendix in 1927 where they manufactured Safety Servo vacuum brakes. It is also known to be the first to introduce many braking technologies to North America, such as: air compressors, air dryers, and ABS. Bendix later took the automotive air brake worldwide by signing licensing agreements with Westinghouse companies in France, Germany, Italy and England. Due to WWII, the advancement of air braking was accelerated and soon became standard on heavy trucks, tractor-trailers, fire trucks, and off-highway vehicles.

To this day, Bendix is furthering the development of technology in the commercial vehicle industry. The company recently released a commitment they are making to increase knowledge about the changing landscape of electric commercial vehicles by changing their product strategies to meet the needs of the upcoming vehicles. Bendix is also dedicated to helping fleet and vehicle operators understand the new technology and maintenance that goes along with it so that an organization can make an informed decision on if or when to make the transition to using an all-electric fleet.

Today, Bendix offers many different products designed to make heavy trucks safer and more reliable. Iron Wing Sales has many Bendix braking system components available for purchase!
