Modern Valve Technology

Details :

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 characteristics. 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 five-day Modern Valve Technology training course will address topics including:

  • Valve types; Control Valves, Non-Return Valves and Safety Valves
  • Valve Operation and Control
  • Valve Selection and Sizing
  • Valve Maintenance and Troubleshooting
  • An understanding of valve characteristics and different parameters affecting the operation of valves
  • Knowledge of the main types of valves and the ability to select the right valve for the particular application including Control Valves, Non-Return Valves and Safety Valves
  • The ability to perform the necessary calculation for valve sizing
  • Knowledge of valve control systems including actuators and positioners
