Abstract
A brake control valve arrangement for controlling application of a braking force includes an electro-pneumatic brake control valve block including a hold valve and a vent valve (PRESSURE CONTROLLER), a main regulator valve (RELAY VALVE) and an emergency and a variable load control pressure regulator. The valve block has an inlet for a brake supply pressure, and an outlet in pneumatic connection with a brake cylinder. A pilot pressure into the main regulator valve from the variable load control pressure regulator is controlled by a remote release solenoid valve (CONTROL CHAMBER VENT MAGNET VALVE). The remote release solenoid valve adapted to vent brake cylinder pressure to atmosphere when de-energized thereby enabling release of the wheel braking force via the main regulator valve.
