Intended Application
- Front Axle/Steering for Trucks and Heavy Commercial Vehicles. Its primary function is to reduce brake application pressure on the front axle during normal braking, preventing lock-ups and improving vehicle stability. This type of valve is common in pneumatic brake systems on trucks and buses, especially those with air brake systems that require precise control of the pressure applied to the front brake chambers.
