Safer Cryogenic Ball Valves

Emerson’s latest innovation, AEV C-Ball Valves, is set to revolutionize the way you think about ball valves in the isolation of your cryogenic and severe service processes. With its breakthrough “C” shaped ball design, the ²XC™ ball valve delivers unrivalled torque seated isolation, with improved safety, reliability, and performance.

What is a Double Eccentric C-Ball Valve?

A double eccentric C-ball valve is similar in principle to a conventional ball valve, but with a half ball that makes a “C” shape. This C-shaped ball rotates on two planes of motion with energy from the stem to close and seal against a fixed seat.

Emerson’s advanced AEV design provides superior sealing performance, eliminates the problematic conventional ball valve cavity and lasts longer with an open and closing action that is contactless until the point of sealing.

Revolutionary Yet Proven Technology

Enabled by a unique “C” ball shape and double eccentric design, the ²XC ball valve acts along two vectors of movement to allow opening and closing of the valve without friction or wearing at the seat and “C” contact.

At close, a zero leakage metal to metal seal is formed by cam effect, one full order of magnitude greater than the prevailing industry standard (BS6364), assuring an ultra tight mechanical seal.

Sealing energy is transmitted through the stem and against a fixed seat, eliminating the need for lipseals, springs, or dynamic seals. This results in superior, reliable, uniform sealing performance at high and low pressures in an inherently fire safe design.

The C shape also eliminates the ball cavity of traditional valves, removing the risk of catastrophic failure due to the expansion of unstable trapped product in a true bi-directional design.
Run your processes for longer with the double offset low friction motion that minimizes wear. In severe service, the seal design also ensures no media can accumulate and harden between the seat and body, preventing a leading cause of valve failure.
