Which valve belongs here, and why.
Most valve training teaches a catalogue: what each valve is called, how it is built, which standard it is made to. That is useful, and it is not enough. The engineer standing in front of a P&ID, a data sheet or a failed installation has a different question, which valve belongs at this point in the process, and why that one rather than another.
This programme is built to answer that question. Over seventeen chapters it works through every valve family in turn, asking the same three things of each: what problem does this design solve, what does it do badly, and where does it belong. It then brings all of it together as a selection logic that can be applied to any point in any process.
It is delivered entirely in English, entirely online through our Moodle learning platform, and it includes the printed book, 312 pages, ISBN 978-618-84076-9-5, which is yours to keep.
WHAT YOU WILL LEARN
Seventeen chapters, in five stages.
| Stage | Chapters | What it covers |
| Foundations | 1–2 | What a valve is and what it must do; the pressure boundary, the trim and the API trim charts; how a valve is designated and specified |
| The valve families | 3–10 | Gate, globe, check, plug, ball, butterfly, needle and pinch valves. For each: construction, operating principle, where it excels, where it must not be used, the applicable standards, and a selection guide for oil and gas, refining and thermal power |
| The self-acting devices | 11–13 | Pressure relief valves, regulators and steam traps, devices that work without an operator, each for a different reason. Set pressure, accumulation and blowdown; droop and lock-up; condensate removal and the two failure modes of a steam trap |
| Control and automation | 14–15 | Control valves: Cv and Kv sizing, inherent and installed flow characteristics, cavitation, flashing, choked flow and noise. Actuation: torque and thrust, pneumatic, hydraulic and electric actuators, fail-safe philosophy, solenoids, ESD and the SIL framework |
| Reference and selection | 16–17 | Materials and metallurgy, testing and certification, pressure–temperature ratings and the ASME/API to ISO/EN harmonisation. Then the selection matrix: twelve process functions against every valve type, for liquid and for gas |
Every chapter closes with a selection guide for the three sectors this programme addresses: oil and gas, refining and petrochemical, and thermal power.
WHO IT IS FOR
- Mechanical, process and piping engineers who specify or review valve selections
- Maintenance and reliability engineers responsible for valve performance in service
- Inspection and QA/QC personnel who verify valve construction, testing and certification
- Procurement and technical sales staff who must read and write valve data sheets
- Operators and technicians moving into a technical or supervisory role

HOW TO ENROL
| Step | What happens |
| 1 Apply | Submit the application form together with a copy of your identity document and proof of payment |
| 2 Confirmation | We confirm your enrolment once the application and the payment have been verified |

THE SERIES
This is the first of three volumes. Each applies the same method, teaching by function rather than by catalogue, to a different part of the same question: what the equipment is, how it appears on the diagram, and how it is built in space.
| Volume | Status | |
| 1 | Valves in Oil, Gas and Power | Available now |
| 2 | How to Read a P&ID | In preparation |
| 3 | Isometric Drawings | In preparation |
PRACTICAL DETAILS
| Language | The programme, the book and the examination are entirely in English |
| Delivery | Fully online, through the Welding Greek Institute Moodle platform |
| Access period | 30 calendar days from activation |
