Process Control Valves: Sizing, Selection & Application


1-day course

CPD Credit: 6.5 hours, C1

Course Overview

This course will provide an insight to control valves which is typically the final control element in the control loop. It will review the principles of control valves, actuators, positioners, and related accessories.

Each delegate will learn through active participation using exercises and practical sessions covering the different types of control valves.

Valve sizing will be done to ANSI/ISA 75 and IEC 60534 standards for both compressible and incompressible applications. This will ensure that control valves are appropriately sized, selected and operated for end use.

Course Aim

The primary objective is to give each delegate a practical understanding of valves, actuators, and accessories through a comprehensive look at the design and application of valves as an integral part of the piping system.

Control valves as the final control element in a process control system will be covered as well as essential maintenance and installation guidance.

The course will cover, but is not limited to:

Introduction to control valves

Control valve Types – Sliding Stem or Rotary

Actuators – Diaphragm, Piston and Rotary

Comparison of Control Valves and Actuator types

Packing types and application

Positioners types and application, I/P converter

Compressible and Incompressible Valve Sizing – Manual and Software

Control Valve Characteristics – Inherent and Installed

Control Valve Cavitation, Erosion and Flashing

Control Valve Noise

Severe Service Control Valves

Valve Application Guidelines

Control Valve Data Sheet

Installation and Maintenance

Who Should Attend?

This course is focused to the needs of chemical, instrumentation, maintenance, and mechanical engineers and technicians working with pumps across the biopharma, food, water and wastewater, chemical and power generation sectors.
