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. Cavity fillers are supplied in PTFE and TFM materials.
