Description

What does an unloader valve do?

This unloader valve plays a critical role in the pneumatic braking system by regulating air pressure and managing the compressor's load cycles. Constructed from high-strength components, it ensures reliable operation under the demanding conditions of heavy commercial vehicles.

Vehicle and engine compatibility

Designed specifically for MAN trucks, this component maintains optimal pressure levels within the air circuit. It is compatible with MAN systems and ensures precise control during the inflation and cut-out phases of the braking cycle.

Installation and maintenance

The unit features specific port dimensions, including M22x1.5 and M12x1.5 connections, to ensure a secure fit within the existing air lines. Technicians should verify port sizes and cut-out pressure requirements (8.1 BAR / 0.2 BAR) during installation to guarantee system integrity.

System reliability

Regular inspection of the valve and its connections is recommended to prevent pressure drops in the air brake system. Consult your authorized distributor for further assistance.

OE cross-reference

301.01.0002 (Unloader Valve) is the equivalent of the MAN OE number. This part directly replaces MAN OE number 84521019017.
