It manages the application and release of spring brakes on trucks and trailers with protected reservoir systems. Designed with service brake priority, it prevents compounding of the spring brake and service brake forces. The valve uses a 3/8-inch NPT control port and standard cover plate orientation to ensure reliable, predictable brake response.
