This 4-hour quick book provides an overview of control valve with emphasis on the sizing and selection. This course is for mechanical, instrumentation and process engineers involved in sizing, selecting and applying process control valves. No Price: $ The most efficient valve is one with a linear flow characteristic hence efforts are made during the valve sizing process to approximate as possible to a linear flow characteristic. The most common types of plugs are the equal percentage, linear, and quick opening plug.

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 “flow regulating” type. It consists of 23 chapters written by a number of respected control valve experts.
Here is a list of the chapters that are included: 1. Introduction to Control Valves 2. The History of Control Valves 3. Terminology 4. Valve Bodies 5. Control Valve Actuators 6.
Sizing 7. Cavitation and Flashing 8. Control Valve. Control valves should not be less than half the pipe size. Normally the valves exclusively envisaged for shut-off service shall be line size. Alternatively, they could be sized as control valves.
In the case of lines with a diameter of up to 1″ the valve size shall normally equal that of the line. In the case of lines with a diameter larger.
Control Valve Sizing. The successful operation of process plant and systems involves the highest level of measurement and control performance.
Control valves therefore perform a key function in this process. The performance of control valves can have a dramatic effect on plant operating efficiency, overall profitability and asset life cycle costs.

Control. When control valve professionals talk about "control valve sizing," they really mean the entire process of selecting the valve that will do the best job of controlling the process. Selecting the right size valve is an important part of the process, but there are other equally important considerations as well.

Norriseal’s Valve Sizing Program will accurately calculate the CV, flow velocity and flow noise.
The program will also show messages when unusual conditions occur such as cavitation, flashing, high velocity or high noise. The results from Norriseal’s Valve Sizing Program are only one element. determines the final valve size. No formulas, only good common sense combined with experience, can solve this problem.
Operating Conditions This handbook on control valve sizing is based on the use of nomenclature and sizing equations from ISA Standard S and IEC Standard Additional explanations and supportive information are. Valve applications with fairly consistent inlet pressures, such as process control and power applications are usually sized at 90%.
The valve specifier usually accepts this as a fair margin of safety in stated sizing conditions. THIS BOOK WAS DEVELOPED BY IDC TECHNOLOGIES.

An important performance metric for control valves is noise production expressed in decibels (dB). In most control valves, the dominant mechanism of energy dissipation comes as a result of turbulence introduced to the fluid as it travels through constrictive portions of the valve trim.
Basics of Control Valve Sizing. Control valves often determine the capability of the control system, and a poorly sized and selected control valve will make tight control impossible regardless of the control strategy or tuning employed.
Selecting the right valve matters. There are several aspects of sizing/selecting a control valve.
