Our History

Established in 1971 by an industry veteran, Vonberg began offering innovative and proprietary solutions to the material handling industry. The development of the exclusive Surges Internally Dampened (S.I.D.) feature brought Vonberg flow regulators to the forefront of load lowering applications.

In 1990, Vonberg expanded the product line to include cartridge valves as a complement to the already established in-line valve offerings. These complementary lines developed and grew into the fully featured catalog of in-line, cartridge, and custom valves that Vonberg designs and manufactures for major producers of mobile and industrial hydraulic equipment. The product is sold nationally, and internationally, directly to OEM’s as well as through a networkof authorized distributors. Vonberg is an independent, non-union, family owned and operated company dedicated to timely delivery of innovative, competitively priced, quality products.
