Crispin Valve began in 1905 with an Air Valve designed by company founder, Clarence Crispin. 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. 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. Additionally, no other valve company can match our commitment to superior customer service. 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.
