Description

What does a relay valve do?

This relay valve functions as a critical component within the compressed air brake system, managing rapid air pressure transfer triggered by a pilot signal. It is manufactured using high-strength components to ensure durability under the rigorous operating conditions of heavy commercial vehicle braking cycles.

Vehicle compatibility

The unit is specifically designed to be compatible with Mercedes-Benz vehicles. It serves as a reliable replacement to maintain optimal braking performance in trucks and heavy duty machinery where precise pneumatic control is required.

Installation and maintenance

Installation requires careful attention to the M22x1.5 VOSS and M16x1.5 VOSS port connections to ensure airtight integrity. Technicians should verify that the system pressure does not exceed the 10 BAR maximum operating limit during testing to prevent component fatigue.

System troubleshooting

Consult your authorized distributor to ensure correct fitment for your specific vehicle application.
