The air pressure regulator AR-11 (also known as the “soldier”) is an important element of the pneumatic system of HTZ tractors and ZIL vehicles.

In the catalogs it goes under the number AR11-3512010 for T-150 tractors and 130.3512010 for ZIL cars.

It is installed in the compressed air supply line between the compressor and the pneumatic brake system. The design includes two housings separated by a diaphragm, a filter, a pusher with a spring, a valve with a spring and a seat. It works on the principle of pressure stabilization: when it reaches a predetermined level, the valve shuts off the air supply, preventing excess pressure in the system.

The AR-11 regulator is used on tractors T-150, T-151, T-156, HTZ-17221 and other models. It works in tandem with compressors 540-3509015 (tractors) or 130-3509012 (ZIL), ensuring stable and safe operation of the brake system and other pneumatic consumers.

Thanks to its durable metal construction, the regulator is reliable and durable, resistant to vibrations and temperature changes. Its versatility allows it to be used on both agricultural machinery and trucks. Simplicity of installation and availability of repair kits make it convenient for maintenance and repair.
