Valve positioners are typically pneumatic or analog i/p and are used when a valve requires throttling action. Electronic valve positioners, such as the fisher model dvc6000, use an electronic sensor to detect valve stem position, a microprocessor to compare that sensed stem position against the control signal by mathematical subtraction (error = position − signal), then a pneumatic signal converter and relay (s) to send air pressure to the valve actuator.

Valve positioners are used when the 0.2 to 1 bar pressure in the diaphragm chamber is not able to cope with friction and high differential pressures. A valve positioner relates the input signal and the valve position, and will provide any output pressure to the actuator to satisfy this relationship, according to the requirements of the valve, and within the limitations of the maximum supply pressure.

Electronic valve positioners, such as the fisher model dvc6000, use an electronic sensor to detect valve stem position, a microprocessor to compare that sensed stem position against the control signal by mathematical subtraction (error = position − signal), then a pneumatic signal converter and relay (s) to send air pressure to the valve actuator. Electric actuatorsfeature visual and electrical valve position indication, manual override, and weatherproof enclosures.

Electronic valve positioners, such as the fisher model dvc6000, use an electronic sensor to detect valve stem position, a microprocessor to compare that sensed stem position against the control signal by mathematical subtraction (error = position − signal), then a pneumatic signal converter and relay (s) to send air pressure to the valve actuator. They perform the same function as pneumatic positioners do, but use electricity instead of air pressure as an input signal. Intelligent valve positioner, which is mainly used in the fluid process control system, achieves valve flow adjustment control.
