Optimize your trailer’s safety and air system efficiency with the Sealco 110171 Spring Brake Control Valve. This "Protected Reservoir" style valve is specifically designed to manage the application and release of spring brakes while ensuring that the air reservoir is protected from total pressure loss in the event of a supply line failure.
A key design feature of the 110171 is its parallel port configuration, where the control and supply ports are aligned parallel to the reservoir ports, allowing for cleaner plumbing and easier installation in tight chassis spaces.
