FAQs
A control valve positioner is typically pneumatic or analog I/P and is used when a valve requires throttling action. It delivers pressurized air to the valve actuator so that the position of the valve stem or shaft corresponds to the set point from the control system.
While a control valve positioner serves a single purpose, which is to maintain a valve at its intended control position, digital valve controllers, through their digital design, provide much more. A digital valve controller is a microprocessor-based instrument that is compatible with a variety of communication protocols, including HART, FOUNDATION fieldbus, and PROFIBUS. The microprocessor enables diagnostics and two-way communication to simplify setup and troubleshooting.
Emerson has a host of new innovative solutions that are transforming the way valves installed in industrial applications interact with end users worldwide. These solutions are grouped into the four main areas.
