Digital Valve Controllers
Meet your process reliability and performance goals by bringing intelligence to your entire valve assembly.
What is a Digital Valve Controller?
This type of positioner 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. In a typical digital valve controller, the control signal is read by the microprocessor, processed by a digital algorithm, and converted into a drive current signal to the I/P converter. The microprocessor performs the position control algorithm rather than a mechanical beam, cam, and flapper assembly.
