The packing fits a wide range of block valves and can handle any valve sealing applications where a graphite stem packing is suitable. So, standardizing on it can cut packing inventory, reduce chances of error in packing selection and simplify installation.
Plants can use 1622 packing to comply with U.S. Environmental Protection Agency consent degrees requiring "low leak valve packing technology" to remedy non-complying valves.
Mobile Software Eases Valve Maintenance
ValveLink Mobile software provides the capability to set up, calibrate and troubleshoot Fisher Fieldvue DVC6200 and DVC6000 digital valve controllers using a Field Communicator, personal digital assistant (PDA) or smart phone. It supports HART communications, advanced diagnostics, performance diagnostics and optimized digital valve levels on both lines of controllers.
The application, which was commercialized in December 2009, simplifies access to control valve data and requires no special training. The software affords easy navigation through its flick, zoom-in and zoom-out capabilities. Its modern, intuitive interface makes it easy to streamline control valve maintenance activities and optimize process control operations. Users gain access to existing fieldwork tools and maintenance practices via large touch-screen icons. A touch of an icon allows setting up and calibrating valve assemblies, monitoring status and alerts, stroking a valve, performing a step test, running a valve signature, and viewing and saving diagnostic tests. Data also can be uploaded to the control system for additional evaluation.
ValveLink Mobile integrates easily into current field diagnostic systems and plant work practices. It provides safe and convenient access to hard-to-reach valves using a Bluetooth HART modem.
The software can be downloaded to 375 and 475 Field Communicators via the Easy Upgrade Utility. Because those communicators are intrinsically safe, users can take advantage of the software when working on digital valve controllers located in hazardous areas. It also may be installed on any PDA or smartphone running Windows Mobile 5.0 or newer (but not Windows Phone 7).
