With roots stretching back to 1878, Clow Valve Company is one of the most experienced manufacturers of hydrants and valves in the country. We have dual locations operating in Oskaloosa, Iowa, and Corona, California. that serve customers across the country. Modern facilities and cutting-edge technologies have helped make Clow Valve an economic, environmental and community leader. We are proud to continue our history of offering manufactured products that are made at home, right here in the USA.

At our two locations, Clow works to provide our customers with the very best products for waterworks and waste waterworks infrastructure. Our Oskaloosa plants include iron and brass foundries, a machine shop, assembly, finished goods warehousing, shipping and administrative offices. Our Corona plant manufactures and assembles wet barrel fire hydrants and maintains inventories of other Clow products. By maintaining the highest safety standards and environmental regulations at both locations, Clow has created a working environment that creates positive change for our workers and our communities.

Thanks, in part, to our advanced facilities we produce a wide variety of high-quality products. Whether it’s an Eddy hydrant, an eccentric plug valve, or a resilient wedge valve, we manufacture quality products for customers across the country to a variety of AWWA, NSF, UL and FM requirements and specifications. Our products are American made and American owned. While other companies have moved overseas, Clow has invested millions of dollars to create safe and modernized facilities where our American workers can thrive. Because at Clow we believe if something is worth doing, it’s worth doing right.
