WebA pneumatic actuator applies force as a function of air pressure and piston/diaphragm area (F = PA), and the spring in turn compresses or stretches to generate an equal and opposite reaction force. The end-result is that actuator pressure linearly translates into valve stem motion (x = PA/k ). WebSo the pneumatic positioner will receive a control signal and translates that into the appropriate pneumatic output signal to the control valve actuator. In pneumatics air or gas is used to operate a mechanical device. After receiving the signal from the controller the positioner outputs air pressure as directed.
