Electric Actuators

General Applications

The EPI2 electric actuator is available in six sizes and is designed for on/off or modulating control of the valve that the actuator is mounted to. The actuator is suitable for installation in a wide range of plants, including heavy industrial, chemical, petrochemical, and onshore/offshore Oil and Gas installations.

Features

· Low- or high-voltage power supply (DC, single-phase AC, or three-phase AC)

· Multiple adjustable stroking times to suit specific applications

· Interchangeable base plate and range of shaft inserts enable simple connection to any valve type

· Over-temperature protection is provided by a sensor located within the control enclosure, as to limit the temperature of the motor and control system

· Epicyclical gearing ensures reliable and smooth operation

· Top-mounted position indicator

· Constantly-engaged manual override (for use when power is lost), featuring a handwheel that does not rotate while the motor is in operation ·Optional local control panel for manual valve operation with additional open/closed indicator

· Simple upgrade options for modulating control and network communication via DeviceNet or Profibus DP protocols

· Latched-type output contacts for fully open/ fully closed remote indication. Output contacts for monitor and blinker/local selector indication are also available
