New Line of CE/CSA Approved Reversing, Quarter-Turn Actuators
April 14, 2010
Available in both on/off and proportional control models, the actuators are designed for use with all ball and butterfly valves up to 24-percent in size and torque outputs from 300 - 13,500 in. lbs. Unique features include a modular design that utilizes US-manufactured modular PC boards to eliminate 90-percent of internal wiring for higher quality, reliability, and easier maintenance, and a superior epicyclical gear design. Proportional control model added features include advanced thermal management that utilizes proprietary microprocessor-based algorithms to automatically control motor temperatures in real-time with close-loop feedback, and user-selectable data logging and diagnostics for a variety of control functions through use of a simple joystick/menu interface. Other standard features include four limit switches (two auxiliary) internal low power heater, position indicator, self-locking drive, clutch-less manual override, thermal overload protection, ISO 5211 mounting base, and choice of operating voltages.
