The Sensotronic Brake Control (SBC) system operates using a hydraulic high-pressure reservoir to supply brake fluid. A piston pump, driven by an electric motor, generates controlled brake fluid pressure ranging between 140 bars (2,000 psi) and 160 bars (2,300 psi) in the gas diaphragm reservoir. [2] When the brakes are engaged, the SBC control ...
The most common final control element in the process control industries is the control valve. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds, to compensate for the load disturbance and keep the regulated process variable as close as possible to the desired set point.

Description. An exhaust brake is a valve which essentially creates a back-pressure in the exhaust system, which applies enough force onto the engine's pistons to slow the engine. In most cases, an exhaust brake is so effective that it can slow a heavily-loaded vehicle on a downgrade without ever applying the vehicle’s service brakes.
Anti-lock braking system. Symbol for ABS. ABS brakes on a BMW motorcycle. An anti-lock braking system ( ABS) is a safety anti- skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [ 1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact ...
Relay valve. A relay valve is an air-operated valve typically used in air brake systems to remotely control the brakes at the rear of a heavy truck or semi-trailer in a tractor-trailer combination. Relay valves are necessary in heavy trucks in order to speed-up rear-brake application and release, since air takes longer to travel to the rear of ...
When the compressor is operated the shuttle valves direct air to open the brake shoes. When the control valve is centered, the brake cylinder is vented through the shuttle valve, and the brake shoes are allowed to close. [clarification needed] Air pilot control: converting from air to oil results in locking of the cylinder.
When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders.
