The Clarkson KGD wafer style slurry knife gate valve offers the latest in elastomer technology with an all-new sleeve design.
All-New KGD Mark III Sleeve.
As a result of our never-ending desire for continual improvement, Tyco Flow Control is pleased to introduce the all-new KGD Mark III Slurry Valve Sleeve from Clarkson. The Mark III incorporates advanced features gained from thousands of installed Clarkson KGD slurry valves over the past 15 years, giving you a better overall performer with additional features:
- Each sleeve incorporates a more robust support disc into a one-piece design which resists over-compression of the sleeve
- Internal profile of sleeve provides a pressure assist to the sealing function
- Sleeve profile reduces drag and provides longer service life
- Easier installation in a variety of pipe styles
- Tests show lower installation torque requirements
- The Mark III sleeve can be installed in any existing KGD valve, allowing hassle-free upgrade to the new technology
