Training Certificate

Prolific Consultants FZE Certificate of Course Completion will be issued to all attendees.

Course Introduction

In today's ever-changing environment, the specifier and valve buyer will spend 67% to 80% of their time looking up information. This results in your time being non-productive. This workshop will show you how to circumvent this problem. Industry needs to select the best Valve with the quality it requires in a timely and economical manner. This workshop presents a practical approach to valve selection for the function, Servicing, sizing, installation, repair, overhaul, upgrading and modifications of these components. Valves usually appear to be simple in form and operation, such as those of a manual Off-On Valve, Check Valve, or the Fixed Valve type such as an Orifice, Blind, etc. You will discover that even these components are frequently installed improperly throughout the industry.

Course Objective

This workshop has been structured to show how more than 32 basic types of Valves operate and how they are configured for their many applications. With over 400 classifications for valves produced by more than two thousand manufacturing companies, which Valve do you select? It will be shown how valves should be specified and selected. This workshop will present many accessories such as actuators and how they are made available and selected. Other amenities such as proportional controllers, solenoids, positioners and indicators will also be presented.

In light of the many liability cases held throughout the world, selecting the proper valve can have major consequences for a company's safety, economy and viability.

With this in mind, this workshop is designed to give both the new and experienced user some insight to problems that valve designers and manufacturing facilities encounter in the real world.

Guidelines and numerous "rule of thumb" suggestions will be given to help you make sound choices that limit downtime.

Suitable For

This workshop is intended for Maintenance Engineers, Application Engineers, Inspection Engineers, Elect/Electronics Engineers, Control Systems and Instrumentation Engineers, Production Engineers, Well-Head & Drilling Engineers and the new Valve Designers.
 

This workshop is primarily for those who are new to the field, but it will also serve as a refresher workshop for those who have many years of experience

Training Methodology

A highly interactive combination of lecture and discussion sessions will be managed to maximize the amount and quality of information, knowledge and experience transfer. The sessions will start by raising the most relevant questions, and motivate everybody finding the right answers. The attendants will also be encouraged to raise more of their own questions and to share developing the right answers using their own analysis and experience.

All presentations are made in excellent colorful power point. Very useful Course Materials will be given.
