Flange fully welded ball valve design benefits.
1. the ball valve design includes an electric conductive connection between the internal parts of the ball valve and the body, providing the anti-static function.
2. Long cycle life, Low torques, Locking devices optional.
3. Welded Body Construction eliminates body flanges, reduces potential leak paths and increases resistance to pipeline stresses. Also beneficial in fugitive emission and vacuum applications.
4. Double Body Sealing ensures positive body joint sealing against pipeline stresses. Also beneficial in fugitive emission and vacuum applications.
5. Self Relieving seats for body cavity pressure relief.
6. Fully enclosed spiral wound graphite filled stainless body gasket.
7. Emergency Seat and Stem sealant injection systems offered on most valves.
8. Valves with extended stems, valves for underground applications etc.
