Fisher 1077 Manual Handwheel Actuator
Fisher 1077 manual-only handwheel actuators are intended for use with rotary-shaft valves. Torque is transmitted from the handwheel through the handwheel input shaft to a worm and drive sleeve gear (sector) with splined bore. The worm and drive sleeve gear multiply the torque and transmit it to a splined valve shaft or splined stub shaft.
Features
1.Splined valve shaft mates directly with the drive gear sleeve, reducing the number of parts required and simplifying installation and maintenance.
2.Handwheel rotation direction required to open the valve disk or ball is marked on the handwheel; the rotation indicator is marked in bold print at the open and closed 3.positions and with bold incremental lines to indicate the valve disk or ball position.
4.When installed according to instructions, clockwise handwheel rotation closes the valve in all applications.
