From Indelac Controls, Inc.

ICI manufactures compact quarter turn electric actuators. The word
compact defines the torque range below 10,000 lb-in (1130 Nm). While
we do offer larger torque actuators and different style actuators like
multi-turn actuators (actuators rotating more than 360 degrees) and linear
actuators (actuators drive that move axially instead of rotary) our niche is
in the compact quarter turn market. ICI actuators are used for on-off
service (valve operated to full open/close position to start or stop flow) as
well as modulating service (valve positioned to throttle or regulate flow).

Products & Services
Valve Actuators
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source.
Electric Valve Actuators
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
Manual Valve Actuators
Manual valve actuators do not require an outside power source. They use a handwheel or lever to drive a series of gears whose ratio results in a higher output torque compared to the input (manual) torque.
