Features & Benefits
- No Cavity between Body and Ball
Low dead volume eliminates sediment build-up and prevents larger particles from being trapped. - Abrasion Resistant
PE ball provides superior abrasion resistance. - Full Port up to 2″
No Obstruction to Flow. No possible hang-up of debris. Suitable for lines where ‘pigging’ is required. - Light Weight
Easy Installation, Minimal stress on piping system. - Compact Dimensions
Will fit where other ball valves will not.
