Williams Air Valves
BRAKE SYSTEMS INC. is carrying on the tradition of Williams Controls quality. Recently purchased from Williams Controls, we own the dies, jigs and fixtures so we are able to control every step of the manufacturing and assembly. We have key engineers formerly with Williams now on staff to insure the continued quality of our products manufactured and assembled in Portland, Oregon USA. Air valves are 100% tested before leaving BSI. As a stocking manufacturer often we can ship same day. Non stock items have little lead time. For more information on our valves check out our air valves page!
