This can and should determine the control valve type. What is the inlet pipe size (diameter) and required flow rates? This can determine a relative valve range size that one should be focused on along ...

In power plants with drum-type boilers and constant-speed main ... r is the dP across only the piping and valves at normal flow, and B is the base dP for the control valve. Minimum Control Valve ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

A new control valve is less vulnerable to damage by high-velocity fluid. Control valves experience significant reaction loads when they regulate choked flow. The highly restrictive, complex flow ...
