Description

What does a relay valve do?

This relay valve serves as a critical component within the compressed air brake system of heavy commercial vehicles. It manages air pressure distribution to ensure consistent braking force and rapid response times during deceleration. Constructed with high-strength components, it is built to withstand the rigorous pressure requirements of professional transport fleets.

Vehicle and engine compatibility

The unit is compatible with Iveco and Irisbus vehicles. It is also suitable for various heavy commercial applications where precise pneumatic control is required. This component ensures reliable operation within the braking circuit of these specific vehicle models.

Installation and maintenance guidance

Installation and maintenance should be performed by a workshop technician. The valve features specific port configurations including M22x1,5 VOSS for primary ports and M16x1,5 VOSS for secondary ports, with a maximum operating pressure of 13 BAR. Ensuring correct thread alignment during assembly is vital for maintaining system integrity.

System maintenance tips

Regular inspection of the pneumatic connections is recommended to prevent air leaks. When replacing the unit, verify that all port sizes match the existing lines to ensure a secure seal within the braking system.
