VALVE TYPES: SELECTION, INSTALLATION AND OPERATION Presenter: John Tonkin

Number of days: 4 Cost: $2800 This course is set at a fundamental to intermediate level and is aimed at individuals who have had some experience with valves but have not had the opportunity to be exposed to some of the finer details of these vital pieces of equipment. There are a number of practical examples and case studies that require the delegate to solve some algebraic equations and draw diagrams and graphs. To this end, he/she should have access to a calculator, (preferably scientific) a ruler and some coloured pens. As there will be discussions centred on computer software, it would be advantageous to have access to a laptop computer.

We strive to tailor our training as close as possible to the delegate’s real life experiences. We therefore encourage delegates to bring to the course data/material pertaining to any valve related problem or novel solution experienced back at the workplace. This adds a fresh and very rewarding aspect to the course for all concerned.

KEY CONCEPTS Valve orifice, Cv, and other hydraulic concepts. Control valves (overview only). Gate, globe, pinch, diaphragm, ball, butterfly valves. Materials of construction. Air release, vacuum breaker and non-return valves. Actuators.

WHO SHOULD ATTEND • Piping Engineers and Designers • Mechanical Engineers • Process Engineers • Plant managers and Engineers

ABOUT THE PRESENTER: JOHN TONKIN

2014 sees John's 44th year in engineering. Initially he had exposure to plant maintenance

(steam, water, pneumatics, ash handling, boilers, turbines and pumping systems) and marine steam plant. A number of years in the selling, commissioning and trouble shooting of pumping systems were followed by nine years in the designing and presenting of training courses which covered the technicalities and marketing of pump sets, pipes, valves, diesel engines and basic electrical systems for pumping plant. An extended period followed in which John's career was focused on the marketing, selling and trouble shooting of pumping systems and submersible electric motors. Through his exposure to the international arena and the development and marketing of new products, John has gained a unique perspective of the fluid movement and control industry. A firm believer in the benefits of high-quality training, John has been at the forefront of training initiatives throughout his career. He can now offer your company the knowledge and skills he has gained over the years, presented in an interactive and practical manner. His courses have drawn a multitude of positive comments, many of which allude to his professional presentation style and the practical examples he offers throughout the training session

In addition to a workbook, the resource material for this course will include material from selected manufactures and suppliers together with links to appropriate websites. Where appropriate, case studies based on in-field experiences will be included. Delegates are encouraged to raise problems they have had in the field with our course leaders in order to gain the maximum benefit from the program. Experience has shown that high levels of delegate participation ensure a rewarding experience for all participants.
