Control Valve Sizing Selection. ACTUATED CONTROL VALVES SIZING GUIDE Griswold Controls.
The Valtek Valves Sizing & Selection Manual is a comprehensive, easy-to-follow reference guide for determining the proper control valve for a particular application. The material follows the sequential order of the typical Valtek Valves quote sheet. Foreword This handbook on control valve sizing is based on the use of nomenclature and sizing equations from ANSI/ISA Standard S75.01.01 and IEC Standard 60534-2-1. Additional explanations and supportive information are provided beyond the content of the standards.
sizing and selecting a control valve for a specific application is generally not well understood. Although there are many factors that need to be taken into account the subject is not difficult to understand if dealt with in a logical manner. We also find that many maintenance problems result from people treating the symptoms of a problem rather than tackling the true cause - a basic Sizing and Selection Made Simple. SelectPro is a quick and simple tool for accurately sizing and selecting valves, actuators, sensors and replacement solutions.
Valve Selection Summary 25 Maximum Temperature and Pressure Ratings 29 Glossary 30 Section Vb1: Valves. 2 Vb1 Engineering Data Book. Vb1 Engineering Data Book 3 Valves 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.

small, fluid viscosity should be considered in each valve selection. Emerson Process Management has developed a nomograph (Figure 2) that provides a viscosity correction factor (F v). It can be applied to the standard C v coefficient to determine a corrected coefficient (C vr) for viscous applications. Finding Valve Size Using the C v determined by the basic liquid sizing equation and the flow FINAL CONTROL AND REGULATE 4 Control Valve Engineering I Course: 1300 CEUs: 3.2 Overview This course is for engineers, technicians and others responsible for the selection,

Vl S Sl T R R 0712 1 INTRODUCTION A Control Valve performs a special task, controlling the flow of fluids so a process variable such as fluid pressure, level Although sizing a valve based on a pressure loss curve can usually achieve a similar size selection as a selection based on velocity, it is not the ideal method. A good control valve will have a lower pressure loss at the same flow
design considerations (e.g. cavitations) and control valve sizing calculations. The equations of this Standard are used to predict the flow rate of a fluid through a valve when all the factors including those related to the fluid and its flowing condition are known, when the. Control Valve Sizing & Selection The selection of a control valve for a particular application requires a number of factors to be taken into consideration, one of which is the operating process conditions.:
