Description:
Air Dispenser for Two-Line Trailer Brake System 11.3531010-71 is used in both Two-Line and Combined Air Brake Systems of trailers and semi-trailers. Operated mechanically and ensures fast and controllable admission of compressed air into trailer's brake chambers. Features a mechanically operated valve for automatic trailer brake release.

It is a improved modification of the Air Dispenser 11.3531010-70, distinguishing by discharged valve system, which allows to decrease initial device sensitivity from 0,045 MPa to 0,03 MPa and consequently to decrease trailer (semi-trailer) air brake abrasion time. A distinguishing feature of this device is improved appearance and lesser steel intensity by using injection casting in body production without a price rise in comparison with 11.3531010-70.

Air Dispenser 11.3531010-71 is interchangeable with the 11.3531010-70 by ports size.

Description
Fast Brake Release Valve 11.3518110 is used in Air Brake Systems of trucks, buses, wheeled tractors, trailers and semi-trailers.

It is designed to decrease brake release time by accelerating air exhaust from actuators at the expense of reduced distance covered by air during exhausting process. Fast Brake Release Valve is compatible with Silencer 11.3590070 produced by PJSC "Poltava Automobile Unit Plant".
