At the end of this seminar participants will have:  

• An understanding of different parameters affecting the operation of valves   

• The ability to select the right valve for the particular application  

• The ability to perform the necessary calculation for valve sizing   

• An understanding of the problems associated with valves like flashing, slamming and water hammer 

• The ability to perform troubleshooting of systems involving valves   

• The ability to decide on the right maintenance plan concerning different types of valves 

Engineers and technicians of mechanical, electrical and chemical engineering will benefit largely from this seminar. Maintenance, operation, and people R and D department are recommended to attend this course.
