THE NEW KED CONTROL VALVE FROM KNORR-BREMSE

KED-DAS NEUE STEUERVENTIL DER KNORR-BREMSE

In autumn 1976 the new development of a graduated-brake control valve from Knorr-Bremse GmbH, the KEd control valve, was presented to the UIC sub-committee for brakes. The article describes its functional and constructional features and the improvements compared with the KEa and KEc control valves introduced in 1953-56. The newly developed accelerator control results in high pulse transmission speeds, even in braking with not yet completely released brakes. The altered charge characteristic of the storage air tank reduces the release time on long trains, and owing to the new design of the maximum pressure limiter the control-valve characteristics are independent of the pressure in the storage air tank. The KEd control valve, which is designed for inspection intervals of up to twelve years, is manufactured in both aluminum and cast iron. The article also describes the stationary and running with the UIC rules. The control valve was accepted for international use by the UIC brakes sub-committee with effect from January 1, 1977.
