In 1869, George Westinghouse, Jr. patented a system that used air pressure to stop trains. Since then, Wabtec has continuously led the industry, improving our brake components to meet car design and operational demands.
The enhanced ABDX® Control Valve delivers more benefits than ever before. The latest update incorporates redesigned main piston diaphragms, upgraded emergency portion slide valves, and service portion graduating valve material. Metal alloy provides enhanced resistance to fretting wear when exposed to severe vibration. These changes improve cold weather performance, offer greater resistance to severe vibration, and provide longer service life.
