Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

From portable oxygen delivery systems and patient monitors to ventilator/respirators and diagnostic tools, pneumatic solenoid valves are widely used to control the flow, direction, and pressure of ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

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 deep dive into the technological progress of today’s smart valves, bearings, brakes, gearboxes and actuators, and what’s next. A robotic arm with three Ogura spring-applied brakes on the pivot ...
