Continuing our focus on quality products!
BSI & Williams Air Valves
A new addition to BSI, we now manufacture a wide range of Air Valve Products. Producing 90 air valve and air treadle assemblies allows us to provide over 900 piece parts and repair kits formerly available from Williams Controls. We also stock many other part numbers as conversions of existing factory products, you can download our current catalog but always feel free to contact us about availability.
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.
Manufactured in Oregon!
