ODL Series are compact, intelligent quarter turn electric actuators for the accurate control of valves with torques up to 2000 N.m. ODL is designed for on/off or modulating control of butterfly, ball, rotary plug valves or dampers in a wide range of heavy industrial, chemical and petrochemical plants, water treatment plants, on and offshore. It can be driven by 380V/220V/110V AC power or 24V/110V DC power, inputs 4-20mA current signal or 0-10V DC voltage signal as control signal. (CE certificate approved).

How dose modulating electric actuator work:

An electric actuator is a device that converts electrical energy into mechanical energy. It is used to control the motion of a valve or a damper in order to regulate flow or pressure. Modulating electric actuators work by controlling the position of a valve or damper over a range of outputs. This means that they can adjust the flow or pressure of a fluid depending on the input signal that they receive.

The modulating electric actuator consists of an electric motor, gear train, position feedback sensor, and electronic control circuitry. The electric motor provides the mechanical force required to move the valve or damper. The gear train helps to amplify the output torque of the motor, making it powerful enough to move the valve or damper.

The position feedback sensor is used to determine the actual position of the valve or damper. This information is then fed back to the electronic control circuitry, which compares it to the desired position as indicated by the input signal. If there is any discrepancy between the actual and desired positions, the control circuitry adjusts the motor output until the valve or damper reaches the correct position.

The input signal to the modulating electric actuator can come from a variety of sources. For example, it could be a manual command from an operator, a signal from a remote control system, or a signal from a process control system. The actuator can then respond to this signal by adjusting the position of the valve or damper to the required setting.

Overall, a modulating electric actuator is a highly precise and reliable way of regulating fluid flows and pressures in industrial applications.
