Reversing Quarter-Turn Actuators are CE- and CSA-approved.

Press Release Summary:




Offered in on/off and proportional control models, EPM Series is designed for use with up to 24 in. ball and butterfly valves and torque outputs from 300-13,500 lb-in. Electric actuators utilize modular PCBs and epicyclical gear design to minimize wiring and provide dependable torque transmission. Proportional control model adds features such as real-time thermal management with close-loop feedback as well as user-selectable data logging and control function diagnostics.



Original Press Release:



New Hayward EPM Series Reversing Quarter-Turn Electric Actuators Look Like Other Electric Actuators on the Outside but Offer Innovative Features on the Inside



Hayward Flow Control Systems, Clemmons, NC, a division of Hayward Industrial Products is offering an innovative new line of CE and CSA Approved reversing, quarter-turn actuators with a number of unique features not found on other electric actuators.

Available in both on/off and proportional control models, EPM Series Actuators are designed for use with all ball and butterfly valves up to 24" in size and torque outputs from 300 - 13,500 in. lbs. Unique EPM features include a modular design that utilizes US-manufactured modular PC boards to eliminate 90% of internal wiring for higher quality, reliability, and easier maintenance, and a superior epicyclical gear design that provides tough, dependable torque transmission in a compact, quiet, smooth package. 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, clutchless manual override, thermal overload protection, ISO 5211 mounting base, and choice of operating voltages. Options include positioners, extended duty motors, 0-90° - 180°, feedback potentiometer, two additional auxiliary switches, local control station, and power supply flexibility.
