Product Overview
The Sealco 9400 is a dependable large-body pressure control valve crafted to regulate air pressure to the delivery port, while bleeding off any excess via its built-in exhaust port. Commonly used on lift axles, tractor tag axles, and pusher axles, it helps maintain consistent, controlled pressure in heavy-duty air brake systems.
Equipped with an adjustable knob allowing fine tuning from 5 to 85 PSI, the 9400 provides precise control. It includes ¼" NPT inlet and outlet ports and a 1/8" NPT exhaust port in a rugged, compact housing.
