EMERSON Process Management has released the Fisher Design GX, a compact and rugged globe-style valve system. It controls a wide range of process liquids, gases, and vapours.
The valve is available with a complete accessory package, including the Fieldvue digital valve controller DVC2000 series. The controller is integral-mounted, requiring no external tubing.
A multi-language product configurator is available to simplify valve sizing and selection. Once the valve has been specified, actuator sizing is automatic. Installation is faster because the GX is small and lightweight. Less commissioning time is required because of the integrated push button instrument and multilingual local user interface. The linkage-free position feedback system eliminates typical calibration problems. Live-loaded packing provides superior stem sealing and extended service life. The actuator instrument mounting is compatible with the IEC 60534-6-1 (NAMUR) mounting standard and the actuator fail action is easily reversed in the field. The optimised GX design uses many common parts throughout the product range to minimise stocking requirements.
The Design GX meets the requirements of both EN and ANSI standards. Valve body sizes range from DN 25 to DN 100 and pressure classes are available in PN 10-40 and Class 150/300. Shutoff can be specified to meet Class IV, V, or VI. Live-loaded PTFE V-ring stem packing is standard. Graphite-based packing and an extension bonnet are available for temperatures above 232ºC. Valve body flow passages are optimised for flow stability and high capacity. A full range of materials is available including alloys.
The Design GX with Fieldvue digital valve controller is a full functionality intelligent digital field device that powers Emerson's PlantWeb digital plant architecture. Online diagnostics performed by the GX with FIELDVUE are monitored by Emerson's AMS predictive maintenance software. They are delivered by PlantWeb to enable those running plants to implement predictive maintenance, anticipating and responding to issues before they impact operations, avoiding shutdowns, and lengthening time between turnarounds.
