Crispin Valve begin in 1905 with an Air Valve designed by company founder, Clarence Crispin. Returning to Berwick, PA after earning an Engineering degree from Cornell University, Clarence wanted to 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 water line drained, all without leaks or breaks in the water’s flow.
Clarence patented his design, and the Air Valve industry was born when he founded Multiplex Manufacturing Company, known today as Crispin Valves. Less than five years later, Crispin Air Valves were installed on the Panama Canal, history’s greatest waterworks project, at the request of Teddy Roosevelt’s Army Corps of Engineers.
No other company in the world today has manufactured Air Valves longer than Crispin, but we’ve also added Check, Butterfly, Plug and Gate valve lines. In all, we manufacture more than 35 valve designs in sizes ranging from ½” thru 168″. And four generations after our founding, we’re still family-owned and American made. We look forward to putting over a century of experience to work on your next valve project.
