Actuators and Positioners

The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals. These control signals, traditionally based on 3-15psi (0.2-1.0bar), more common now are 4-20mA signals for industry, 0-10V for HVAC systems, and the introduction of "Smart" systems, HART, Fieldbus Foundation, and Profibus being the more common protocols.

We are able to provide different type of actuators and positioners that are necessary in flow control systems for each condition and type of usage.

An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and

converts that energy into motion.

Positioners are most commonly used to move a control valve to a specified position so that a process meets specific parameters (flow, pressure, temperature).
