AKH2 - Actuator Sizing Torques
Packingmaterial: chevron PTFE or PTFE-graphite
Size
• for clean and clear application
• for dry and slurry application
* reduced port
- Stated torques are sizing torques. No further safety factors are to be applied against these torques.
- The use of ceramic balls in lined valves will result in 15% higher sizing torques.
- The use of C-Balls or V-Balls does not result in change in sizing torques.
- Stated sizing torques are „Break-Open“ and „Re-Seating“ torques. Running torques are typically 35% below sizing
torques.
- The stated „MAST“ value is the Maximum Allowable Stem Torque. Beyond this value permanent deformation /
destruction of liner is to be expected.
- Please note the service conditions of the pressure- / vacuum-temperature-diagrams: register 1, page 13.
