Introduction

Process Control Valves & Actuators

Objectives

By the end of this GLOBAL FRACNISE training Course participants should be able to:

  • Comprehend the inner operation of most commonly utilized valve types
  • Decide on the best valve to use, for specific applications
  • Determine the most cost effective valve size
  • Determine the best device to drive and operate an assortment of valves
  • Get control valves to operate optimally in the field, using an assortment of techniques

 

WHO SHOULD ATTEND?

This training course is suitable for a wide range of professionals, but would greatly benefit:

  • Key instrumentation personnel involved in valve maintenance
  • Senior management and staff responsible for valve and actuator selection
  • Mechanical and electrical staff that come into contact with valves
  • Process control engineers requiring a high plant availability, often affected by valves
  • Designers, industrial engineers and staff responsible for plant safety
  • All personnel with a vested interest in applications that require / utilize valves
 
 Course Outline

DAY 1

Valve Principals, Purposes, Types, Control Signals and Flow Conditions

  • Valve Principles, Valve Purposes and Control Signals used with Valves
  • Flow Conditions in and around Valves
  • Reynolds Numbers
  • Cavitation and Flashing and How This Influences Valve Selection

DAY 3

Valve Software, Actuators, Positioners, Cavitation & Noise Control & SIS

  • Software Used to Size Control Valves
  • Assorted Actuators and their Properties and Characteristics
  • Valve Positioners
  • Cavitation and Noise Control - in and around valves
  • Valves and How They Fit into Pressure Relief and Safety Instrumented Systems (SIS)
  • Using Digital Controllers - with valves

DAY 4

3-term Controllers and Loop-tuning for Processes Containing Control Valves

  • Understanding and Implementing the Right Controller Action - for fail-safe valves
  • Understanding all of the Variables - associated with three-term control
  • Open Loop Tuning - for controllers that act on control valve loops
  • Closed Loop Tuning - for controllers that act on control valve loops
  • Trial and Error Tuning - to optimize control valve performance

DAY 5

Using Valves in Cascade, Ratio, Dead-Time Dominant, Non-Linear and PLC-Controlled Processes

  • Setting-up a Cascade Loop - using a single valve and multiple controllers
  • Setting-up a Ratio Loop - using a Single Valve and Multiple Process Variables (PVs)
  • Dead Time Dominant Loops - how this affects the valve performance, and how this is corrected
  • Using a Control Valve in a process that exhibits different responses in different zones
  • Combining PLCs - for valve control
