About

For over 50 years, co-ax® application engineers have been designing and building valves for applications ranging from power generation, machine tools, packaging, aerospace, chemical processing and manufacturing. We have been involved in new construction of sophisticated processing plants as well as streamlining existing flow control systems on offshore skids and for remote or hazardous applications. The valve technologies engineered and manufactured by co-ax® are rugged, special-purpose and mission critical valves.

The unique co-ax® valve features pressure balanced design, high cycle life, bubble tight shut-off, bi-directional operation, compact size, low air consumption and actuation speeds as fast as 30 milliseconds. This translates into greater durability, repeatability, precision and performance.
