Cavity Filler for Ball Valves

 

Many of our ball valves can be supplied with full-body cavity fillers. Cavity fillers fill the void normally found behind the ball and the valve body in conventionally designed ball valves. Cavity fillers assures that no media is allowed to become trapped above, below, or around the valve ball or the body cavity. Cavity fillers prevent freezing or seizing, while also reducing the possibility of cross contamination of medias.  Applications involving paint, pigments, or process systems sensitive to cross contamination or crystallization (ex. sodium hypochlorite) benefit from a cavity filler.  These are commonly used for sanitary food, beverage and pharmaceutical applications to ensure thorough CIP sanitization.  Reliability is enhanced for ball valves used for slurry and viscous liquid applications which might dry-out or otherwise impede operation of the valve.  Cavity fillers are supplied in PTFE and TFM materials.
