INTRODUCTION
This course covers the parts and components of different types of valves; the methods of operation and maintenance; the troubleshooting and maintenance used in valves. This course will explain the main types of manual and control valves and their actuators;This course is designed to give trainees a solid, practical understanding of common process control equipment and of the actual concepts and factors involved in setting up, maintaining, tuning, and troubleshooting a variety of valves and their control systems.This course is best suited to candidates who are familiar with basic information on valves; mechanical principles and basic electricity, and have a basic knowledge of instrumentation systems.The course will finish by going back to the start by mentioning and giving examples of process integration, where control valves are employed to utilize fluid flow.
The course is a well structured one and a busy and very much evolved one, the candidate will get the most updated knowledge and they learn the modern techniques in profile solving and in computing appellation.
WORKSHOP OBJECTIVES
- To be able to analyse the fundamental operation parameters and the control systems in all types of valves including the control valves.
- Valves operation and construction; inspection and maintenance
WHO SHOULD ATTEND
New graduated engineers; maintenance personals; static equipment operators, control engineers; instrumentation personals
PROGRAM
DAY 1
Types of control valves and their characteristic & operations mechanism
- Types
- Terms and definitions
- Parts and components
Diaphragm – gives some control and will handle corrosive slurries.
- Effects of control actuators
- Control valves (types, characteristics, Cv sizing)
- Valve actuators (types, fail modes, dead band)
- Variable speed motor controls (DC and AC)
- On / Off control action
- Common problems in process control systems
- Troubleshooting process control systems
Gearboxes: Used to ensure easier operation of larger valves.
Diaphragm valve: A bi-directional valve which is operated by applying an external force to a flexible element, or diaphragm (typically an elastomer).
DAY 2
Operation of all valves
- Application of all valves including the control valves
- Operation: procedure of all valves manual and automatic
Pressure reducing valve is always open with the amount depending upon the required downstream and actual upstream pressures.
Uses of control valves
Relief valve – as a safety valve to prevent excess pressure
- Pressure safety valves
- The difference between PSV’ PRV and the operation principles
Damaging Reducing valve – to control the downstream pressure at a required value.
Location of critical valves
- Actuators
- Codes and fabrication
- Pressure rating valves
Actuators: Device used to open or close or control valves.
Air valves: Valve that is used to control the flow rate of air.
Back-pressure: The pressure exerted on the downstream side of a valve

DAY 4
Manual Valves & Control Valves Design
Valves & Pipe-work
Technical Information
Manufactures standard as well as customized pipes, fittings, and spools according to customer's requirements. The standard product range has been designed to resolve most industrial valves problems.
Selection of control valves type
(Service Temperature; Fluid to be carried; Service Pressure; flow rate …….. etc.
- The Control valves work in oil industry
- The main uses for CV in oil industry are in transport of materials;
- Plant services
- Process materials
The control valve & pipe work joints (Welding, brazing, cementing, flanges, socket and spigot, unions and couplings [screwing], flared and compression joints
Control Valves work fabrication
To keep the cost low by using an expensive corrosion resistant lining to a cheap but strong valve made out of metal that would normally corrode rather than constructing the whole CV out of the expensive material.
CV work lagging
Lagging minimizes heat loss and protects operators from hot surfaces.
- Coating regulations & protection
- Isolation ; Types of fittings
- Installation procedure
Installation procedures
- Safety shear valves under dispensers
- Minimum pipe slope
- Testing the valves system
- Vent line requirements
- Hydrostatic & pneumatic testing
- Types of materials
DAY 5
Maintenance & Inspection
- Diagnostic testing
- Troubleshooting
- Maintenance and repairs
- Inspection - the Control valves & actuators
- Maintenance Inspection, Inspecting Out-of-Service for CV & actuators
- Record Keeping; Scheduling and Preparing for Cleaning, Repairs and Alterations
- Control Valves Cleaning
- Maintaining and Repairing Closures, Channels; stem; seals; seats; discs; and Bonnets;
- Actuator ; gear box Repairs and Alterations -
- Design of a simple control valve
- Overall control valves coefficient
- Single and multiphase flow in control valves
- Methods of calculation
