Applications
Industrial quality electric actuators typically used to automate quarter turn (90º) ball valves, butterfly valves and dampers. The EAC 1 series actuator is quick and easy to install with standard ISO5211 multi-flange mounting and a double square drive.
Operation
Electric actuator uses power-to-open and power-to-close, stays in the last known position with loss of power. On receipt of a continuous voltage signal, the motor runs and via a rugged all metal gear system rotates 90º. The motor is automatically stopped by internal cams striking limit switches. On receipt of a reversing continuous signal, the mo- tor turns in the opposite direction reversing the output drive position.Modulating actuators with electronic positioner use an analog input signal to control the drive output position. Rugged self-locking all metal gear train eliminates the need for additional braking.
