Fisher 1078 Declutchable manual actuator

Fisher™ 1078 manual actuators are declutchable actuators for manual operation of control valves and equipment that use power actuators. The dimensions of these shafts are the same as those used with H mounting adaptations. The stub shaft fits into a square broach in the manual actuator sector and spacers secure the shaft in the appropriate position.

  • Direct mounting to the actuator housing simplifies installation and eliminates the need for yokes and other brackets.
  • A lever-operated eccentric bearing support on the input shaft allows engagement of the worm gear with the sector at any point of rotation. Because the travel indicator components are mounted on a through shaft, accurate travel indication is maintained during manual actuator disengagement or engagement.
  • The disengagement lever is locked in both the engaged and disengaged positions by a detent mechanism, which must be released before the lever can be moved. This provision reduces the possibility of inadvertent or accidental operation. In addition, stop-pins at the fully engaged and fully disengaged positions provide positive limits for lever travel.
