Product Overview
The Sealco 110171 is a robust spring brake control valve designed for protected-reservoir systems, commonly used in trailers built between the mid-1970s and early 1990s. This valve features a service-brake priority design, allowing simultaneous charging of the reservoirs and spring brakes, plus a relay to speed their release.
Expertly built with a 90° cover plate orientation, inlets and control ports in safer inline configurations, and compliance with FMVSS 121 safety standards, the 110171 ensures dependable braking operation—even after a single reservoir failure. It’s a resilient, fleet-ready component built for long-term reliability.
