Practical Valve Technology
Introduction:
Power Plant
and other petrochemical industries do deal with different types of valves. All
piping systems are fitted with valves for controlling purposes or safety
requirements. Understanding the function of each valve type will have an
important reflection on the process quality, equipment and plant reliability
and the economics of the whole activity. Different application needs to select
the appropriate valve type of a particular flow characteristic. Operation of
the valve also affects the system and the process. Understanding the problems
associated with valves is essential for diagnosis and troubleshooting and the
needed maintenance for the particular type of valves. This course will address
all aspects of selection, operation and maintenance and troubleshooting of
industrial valves.
Course
