About the course

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 five-day course 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 Objectives

This course has been structured to show how more than 32 basic types of Valves operate and how they are configured for their m any 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 course will present m any accessories such as actuators and how they are m Ade available and selected. Other amenities such as proportional controllers, solenoids, positioners and indicators will also be presented. In light of the m any liability cases held throughout the world, selecting the proper valve can have m ajar 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 problem is 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 li m it downtime
