Product Overview
The Sealco 110701 is a highly dependable spring brake control valve designed with a service-reservoir priority system to optimize trailer air brake performance. Factory-calibrated to open at 60 PSI, this valve ensures that air is first routed to the service brake circuit before the spring brakes release—enhancing braking consistency and system safety.
Constructed to OEM standards, this component includes four 3/8″ NPT delivery ports and supports simultaneous charging of both reservoirs and spring brakes, enabling quick release and superior performance in heavy-duty trailer applications.
