About Us

Crispin Valve History

Crispin Valve began in 1905 with an Air Valve designed by company founder, Clarence Crispin. Moving back to Berwick, Pennsylvania and out of

Engineering School at Cornell University, Clarence wanted increase output at the family-owned Berwick Water Company. Early attempts sought to pump water through a wood stave pipe that ran along the bed of the local Susquehanna River. However, the pipe kept collapsing, destroyed by an excessive vacuum that formed as the pipe drained. Clarence designed a valve that could release air from a water line while water was running through it, and admit air when the waterline drained, all without leaks or breaks in the water’s flow.

This patented fluid valve became the foundation for the Multiplex Manufacturing Company. Within 5 years, Crispin Air Valves were solving vacuum problems on the Panama Canal–history’s greatest waterworks project.

No other company in the world today has manufactured Air Valves longer than Crispin.  Indeed, we hold the first U.S. design patent for the product. Our line of valves is extensive, capable of meeting whatever our consumers’ needs are. We offer various sizes of over 20+ different valves types. With our exemplary customer service department as well as sales representatives the exact product needed is delivered to the customer.


Today, as a fourth-generation family owned business, Crispin Valve is a modern professional company that is deeply rooted in the traditional values of its early beginnings.

Our products are used in both hemispheres and in almost every country throughout the world.  The breadth of our international experience allows us to understand & provide the flexibility that customers around the globe require.
