5 control valve selection criteria every processor should consider
Increase process productivity by utilizing valve selection criteria for control valves.
Accurately size control valves with these 5 control valve selection criteria
Successful control valve sizing and selection depends on knowing the actual process conditions in which the valve is to be installed. This information is rarely available firsthand. The more assumptions one has to make on flow conditions, the less accurate the control valve sizing is going to be.

Experience matters in valve sizing and selection
All too often, valve sizing and selection tools are based on standard equations and rules of thumb shaped by performance data collected under laboratory conditions. While laboratory data may be considered extremely accurate, they are no substitute for real-world data collected under actual operating conditions over an extended period of time.
Control valves
Control valves are the most important part of any process control loop. Nothing influences the stability of your process like they do. They are critical to the overall performance of your process — especially when reliability and productivity are your primary goals. They are the key to profitable uptime. The right control valve is one that is engineered, manufactured, tested and optimized for your specific application. This is what Neles flow control solutions offer.
Determining the control valve pressure drop for control valve sizing purposes
Our guest writer Jon F. Monsen discusses the correct method for determining the control valve sizing pressure drop when the system already exists or has been designed.
