Born innovators, Humphrey Products led early commercialization of liquid propane gas lighting products. Today, Humphrey is recognized globally as a prominent manufacturer of pneumatic and fluid control products.
All of our products are designed and produced at the Kalamazoo, Michigan headquarters we’ve called home since our founding in 1901.
Not only are our pneumatic control and fluid handling products designed and produced here, 96% of our suppliers are based in the USA, too – most right here in the Great Lakes Region. With such a tight-knit domestic supply chain, the typical turnaround time on our standard valves is less than two weeks.
Our extensive catalog includes more than 7,500 standard valves, components and accessories. We also offer customization on our standard products, as well as custom design and manufacturing of valves and valve systems.
There are more than 200 people on the Humphrey team, with an average tenure of 15 years. Our capabilities include:
We operate on ISO 9001 quality management system standards – a certification we’ve maintained since 1997 – so you can be sure any product you purchase from Humphrey is quality-built by Americans who are proud to uphold the Humphrey tradition of excellence.
Proudly Made in the USA
