Digital valve controller milestone

Emerson Process Management has announced delivery of the 750,000th Fisher Fieldvue digital valve controller. The digital valve controllers were introduced by Emerson in 1994 as part of on-going Fisher valve technology development and innovation. As final control elements, valves are crucial to control, while at the same time existing in the harsh process environments and in contact with diverse flowing media. Emerson drew upon its valve and instrument expertise to develop the microprocessor-based Fieldvue instrument that enables users to monitor valve performance on-line, to collect and trend performance data over time, and to better predict or plan valve maintenance. Through its continuing innovation, Emerson complemented the controllers with Foundation fieldbus communications, advanced valve diagnostics, on-line performance diagnostics, and emergency shutdown digital valve controllers for Safety Instrumented System applications. Emerson also expanded the use of digital valve controllers into the nuclear market by providing a nuclear certified version and a CSA approved DVC6000 instrument for use with natural gas.
