It charges the spring brakes and service brakes simultaneously and includes a relay function to speed up brake release. The valve gives priority to the service brakes and prevents brake compounding, helping meet FMVSS 121 safety standards. It is commonly used on trailers built from the mid-1970s through the early 1990s.
