Accurate calculations of process Cv’s, valve opening percentages, velocity, critical
condition warnings, and predicted noise levels are some of the features provided
by Allagash International’s Control Valve Sizing (CVS) Application. Calculation algorithms,
methods, and equations are in accordance with international standards of ANSI/ISA-75.01.01
(IEC 60534-2-1 Mod)-2007, Flow Equations for Sizing Control Valves, as well as ANSI/ISA-S75-17
- 1989, Control Valve Aerodynamic Noise Prediction.
Allagash International’s Control Valve Sizing (CVS) Application automatically performs a correction of flow rate calculation,
taking into consideration the resistance of installed fittings.
Define multiple operating points for simple what-if scenarios, determining critical
service thresholds, optimum flow rates for minimum and/or maximum % open, and easy
comparison of available control valve technologies.
Using SSL 128-bit encryption insures secure transmission of data in either direction.
