The use of graphical solutions has purposely been held to a minimum since routine sizing should still be done on the popular and practical Masoneilan Valve.
The effect of these types of fittings on the nominal flow coefficient of the control valve can be significant. A correction factor is introduced to account for this effect. Additional factors are introduced to take account of the fluid property characteristics that influence the flow capacity of a control valve. In sizing control valves, using

These design guideline are believed to be as accurate as possible, but are very general and not for specific design cases. They were designed for engineers to do preliminary designs and process specification

CONTROL VALVE BASICS – SIZING & SELECTION. Introduction. A control valve is a power operated device capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from the controlling system. Control valves may be broadly classified by their function as “on-off" type or
The valve is a controlled device that regulates the flow of a liquid or gas in a system. This regulation is accomplished by the varying resistance that the valve introduces into the system as the valve is stroked. As the valve modulates to the closed position the system pressure drop shifts to the valve and reduces the flow in the
INTRODUCTION. Valtek uses a systematic method for selecting body types, sizes, materials, pressure ratings and trim sizes based on flow characteristics. Valtek control valve flow capacity (Cv) is based upon the industry standard, ANSI/ISA S75.01. This standard and the corresponding measuring standards contain.
