Defining Valve Actuators and Positioners

Valve actuators and positioners are integral components within the valve manufacturing industry. Valve actuators are mechanical devices that move and control valves, providing the force necessary to open, close, or modulate them. They can be operated manually, electrically, pneumatically, or hydraulically, depending on the application.

On the other hand, valve positioners are instruments that interface with the actuator to enhance valve performance. They receive a control signal from a process controller and translate it into the actuator’s motion, ensuring the valve’s position accurately corresponds to the command signal.

In the valve manufacturing industry, these components play a critical role. They enable automation, regulate process control, and increase the overall efficiency of the system. Their precise operation ensures the smooth and safe functioning of industrial processes, minimizing risks and maximizing productivity.
