Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling water, chemical treatment, bottom ash and steam turbine control systems.

Noncompensated flow controls are simple valves that meter flow by restricting or throttling. The amount of flow that passes through an orifice and the pressure drop across it are directly related.

Valves and actuators are critical in every aspect of power plant operations, and companies are working to make innovations that will improve performance and reduce costs.

This electro-proportional flow control valve delivers an industry leading flow rate of 114 gpm (431 L/min) and can operate at a maximum pressure of 5000 psi (350 bar).

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 ...

On the background of the model year '94/'95 legal regulations the evaporative emission system and especially the purge flow management has to change significantly. A strategy is shown, which enables ...

Valve selection Choked flow, in and of itself, is not a cause for concern. The confusion stems from the association of choked flow with many negative phenomena that can affect and damage control ...

Tyco Valves & Controls, manufacturer of valves, actuators and controls, announces that it is now called Pentair Valves & Controls. Now part of Pentair Ltd., Pentair Valves & Controls will continue to ...

Researchers have proposed process flow guides for 3D printing of miniature soft pneumatic actuators. Integrating the prints into a robotic system offers potential applications in jet-engine ...
