• Field-reversible, multi-spring diaphragm actuator allows changing of fail-safe action.
  • Multi-spring actuator offers uniform application of actuator forces to control valve as well as reduces height and weight of valve.
  • Actuator, together with positioner, can be rotated a complete 360­ to allow for ease of local operation regardless of valve orientation.
  • Rolling diaphragm offers increased precision and reduced hysteresis compared to stretching diaphragms.
