Control valves for pump protection service

This paper discusses the essential procedures involved in the application of control valves for the protection of pumps operating at low flow conditions.

Control valve exit noise and its use in valve sizing

This technical paper by Alan Glenn briefly describes general aerodynamic noise generation and prediction and, in more detail, the IEC 60534-8-3 exit noise prediction. It further describes noise genera

CVA line to provide new benefits

Rotork’s CVA line of electric valve actuators has been specifically designed to suit the requirements of all types of process control valves. The CVA delivers both linear and quarter-turn output and b

Measurement of the fluid flow load on a globe valve stem

Technical paper, in which the authors describe how a 2” plexiglas globe valve model was built to permit visual observation and measurements of flow-induced force on the stem. An extensive test program

Using computational fluid dynamics to predict cavitation

Computational Fluid Dynamics (CFD) has been used to successfully model fluid flow in fields like aerospace and pump design. In this paper, Alan Glenn and Gifford Decker report how a high end CFD tool
