The History of CPV Manufacturing

The CPV Manufacturing company that exists today has a long and colorful history. Headquartered in beautiful Kennett Square, Pennsylvania, today it is a legendary manufacturing company known all over the world for superior industrial valves. However, our notoriety does not end there. For over 100 years, we have manufactured a wide variety of mechanical components, including high-quality valves, high-pressure couplings, and O-seal valves. Our products are tested to meet the most demanding standards and are suitable for use in many industries, including industrial gas, petrochemical, and ship building. In fact, our products have met the exacting standards of the U.S. Navy and we are proud to work with them.  

Our success in manufacturing did not come easily. We have worked for more than 100 years perfecting our craft, and that has led us to being industry leaders and a trusted supplier. CPV Manufacturing was founded in 1915 by a Pennsylvania Dutch farmer turned machinist, Isaiah G. Engle. He started this company with his own two hands and was driven by his passion to serve his community. Although Engle focused on creating the highest-quality replacement valves for steam-driven reciprocating pumps, that was only the beginning. 

Throughout the years, our dedicated team would provide several breakthroughs in the manufacturing industry and revolutionize industrial valve design and production. In the 1940s, we created the Silent check valve. Because our innovative design prevented damage from reverse flow, water hammer, and even pressure surges, these very valves are still the global standard.

The incredible success of one valve might have been enough for one company, but not CPV Manufacturing. We continued to look for ways to advance manufacturing and design to create the highest-quality products. Our team had another breakthrough just 10 years later as our partnership with the U.S. Navy began to flourish. 

The strict requirements set by the U.S. Navy were the creative environment we needed to find new testing methods using O-ring connections. The new testing methods led us to having a better understanding of the O-ring, which led to the creation of our famous O-Seal valve product line. Today our O-seal valves and fittings are used in a wide variety of plants and industries.
