What is a 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 is offset on two planes to allow a double eccentric motion that achieves sealing by cam effect 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.
This design enables tight sealing that is independent of process pressure and eliminates the need for springs or dynamical seals between the seat and body that are often the root cause of reliability issues in conventional trunnion mounted ball valves.
Emerson’s advanced design provides superior sealing performance and reliable operation with minimal maintenance cost.
How does a C-Ball Valve work?
Design
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.
