History & Product Innovations

 

Founded in 1915 by Isaiah G. Engle, a Pennsylvania Dutch farmer turned skilled machinist, CPV Manufacturing began as a small one-man business dedicated to serving the community. Engle started the company specializing in creating replacement valves for steam-driven reciprocating pumps.

Throughout the years, CPV Manufacturing has worked to revolutionize the manufacturing industry. For example, our Silent Check Valve has improved system performance since the 1940s. These innovative valves were designed to prevent damage from reverse flow, water hammer, and pressure surges. Today, these valves are used all over the world and can even be found in landmarks like the Space Needle in Seattle.

One of CPV Manufacturing’s crowning achievements and innovations was developed about 10 years later. We began working for the US Navy in the 1950s designing and manufacturing high-pressure valve and couplings.

 

To ensure that each part of our products met the stringent requirements of the US Navy, we developed new testing methods using O-ring connections. This allowed us to disassemble and assemble each component to help us test them for quality.

Once we developed a better understanding of the benefits of O-rings, CPV Manufacturing created the famous O-Seal product line. Designed to provide product versatility, these innovative fittings and valves can be used in a variety of platforms, including liquid or gas services. Today, O-Seal valves and fittings are used in numerous plants, including Praxair’s station in Santo Domingo, Mexico, a fully automated gas facility.

Other CPV Manufacturing innovations include:

  • Mark VIII System
  • FloMaster air-operated shutoff valves
  • G-Series stainless steel shutoff, needle, & check valves
