Course Description
The course is designed for participants to understand the principles of the Types, function, Specification and classification of valves. Then cover the valves maintenance, troubleshooting and repair
This course presents a practical approach to the function, servicing, 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
