VALVE AND ACTUATOR TECHNOLOGY Training Course

Introduction

Research studies within the process industry routinely indicate that the fluid control valve is responsible for 60 to 70% of poor-functioning control systems. Furthermore, valves in general are consistently wrongly selected, are regularly misapplied, and are often incorrectly installed. The problems lie not just within the valve itself but also with its associated ancillaries that form the final control element: the valve actuator, I/P converter and positioner.

What you will learn

The course is based on a wealth of experiential knowledge gleaned from the author's experience working within a systems integration company and also feedback from more than 4000 technicians and engineers who have attended the author’s workshops. On successful completion of this workshop delegates will be able to:

• understand the major technologies used in the final control element
• appreciate the basic theory of flow through a control valve
• calculate the valve flow coefficient Cv
• perform flow and system pressure head loss calculations
• gain an overview of the different types of control, shut-off, and check valves
• appreciate the principles of cavitation control and noise reduction
• select optimum materials of construction to avoid corrosion and erosion
• understand the correct requirements for trim selection
• appreciate the differences between inherent and installed characteristics
• understand control valve characterisation and characteristic profiling
• identify ANSI/DN pipe sizes and pressure ratings
• use the control valve seat leakage classifications
• pick the optimum valve-actuator combination
• apply on-line valve testing and diagnostics for deadband and hysteresis, stick-slip and non-linearity
• understand the principles of preventive maintenance through the application of signature analysis
• perform a bench set and calculate actuator spring wind-up
• pick the correct positioner using our set of guidelines
• gain an insight into the application and limitations of safety relief valves

Training methodology

Throughout the workshop, participants will learn through active participation using exercises, questionnaires, and practical simulation sessions covering:

• systems choice
• basic sizing calculations
• computer-based sizing
• maintenance
• diagnostics

Who should attend

Professionals involved in designing, selecting, sizing, specifying, installing, testing, operating and maintaining control valves:
