A worksheet that calculates control valve installed gain can be part of any control valve selection process. For many years, the author has used, and promoted the use of, control valve installed flow ...

In August’s column, I discussed three-way control valves, their associated bypass pipes, and the importance of a balancing valve being located within the bypass pipe. Such balancing valves are needed ...

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.

Scaling is one of the most frequently occurring problems in geothermal power plants and can prohibit the control of well flow if it builds in the well or wellhead. At HS Energy on the Reykjanes ...

On/off valves are basically on/off switches for hydraulic systems. They are typically installed in applications where precise position or speed control is not required. Proportional valves adjust flow ...
