Advanced Valve Technology: Design, Selection, Installation, Applications and Pumps: Design, Operation And Maintenance
Introduction
Advanced Valve Technology: Design, Selection, Installation, Applications and Pumps: Design, Operation And Maintenance
Objectives
This Course 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 course 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 com pany's safety, economy and viability. With this in mind, this Course 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.
Who Should Attend?
This Course 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.
