NPT control ports, which determines how control air volume is distributed to connected spring brake chambers. Port sizing becomes important when response timing needs to remain consistent across multiple axles. Internal sealing surfaces are arranged to limit leakage that can cause delayed release or unintended brake drag. A standard cover plate keeps mounting orientation familiar, avoiding changes to existing bracket layouts. This Sealco 110170 air brake spring brake valve emphasizes stable control behavior rather than added system complexity.
