Valves, Actuators & Pump Control


Valve sizing and specifying software

February 2003 Valves, Actuators & Pump Control

The Firstvue valve-sizing program helps users identify the control valve package best suited to each specific set of service conditions. Firstvue's powerful valve selection features may be used to specify either a single control valve or hundreds with little effort.

Firstvue offers export/import capabilities that allow the user to take advantage of plant engineering, design and maintenance programs such as Intergraph Corporation's Instrument Data Manager IDM and INtools. Firstvue also allows the export and import of data from most other data management systems via comma delimited text files and a simple mapping function. No matter what data management system is used, the export/import feature helps reduce valve engineering time and costs, improves accuracy and expedites project piping design and project schedules.

Valve engineering, sizing and selection is not complete without valve dimensional data. Fisher's Firstvue Autodraw program provides a quick and simple means of providing this dimensional data. By navigating through a series of simple, drop-down selection menus, a user can secure dimensional data via hard copy or electronic format for both 2D and 3D dimensional requirements. The software provides a fast, user-friendly and flexible means for:

* Sizing, selecting and generating valve specifications.

* Data entry and verification.

* Error removal and rework.

* Importing and exporting all ISA spec sheet fields.

Much of the data entry process is automated by providing drop-down lists of possible entries for specific fields. The on-line help screens provide detailed instructions as well as comprehensive engineering data tables, calculations and measurements.

The user may choose from several valve-sizing options, depending upon the amount of information they have, and the level of detail that is required.

* Quick valve sizing - calculates the flow coefficient for one condition.

* Spreadsheet sizing - performs detailed calculations for multiple conditions, all at one time.

* Schematic sizing - calculates downstream pressure, flow, or flow coefficient for one condition.

To finish off the valve selection, the user chooses the report format they want:

* Fisher Spec Sheet that produces Fisher's custom formats for sliding stem actuators, rotary valves, and regulators.

* ISA Spec Sheet that produces an ISA-defined specification sheet for sliding stem and rotary valves.

* Diffuser Spec Sheet that produces a noise abatement diffuser.

Firstvue data files, spec sheets and reports can be used by Alpret sales staff to provide accurate and timely price quotations.
