Although the basic technology for most valves and actuators has remained unchanged, innovative applications and design modifications for problem solving have led to notable improvements in ...

Now another stalwart of the manufacturing industry, the pneumatic actuator control valve, is being revised by one its principal suppliers—Festo. This new design approach, according to Festo, creates ...

The older design valves require constant maintenance and their performance is generally poor. In addition, leaking control valves can reduce a power plant’s output by up to 50 MW. Modern ...

The performance of proportional valves falls in the wide spectrum between on/off solenoid valves and electrohydraulic servovalves. The performance of proportional valves falls in the wide spectrum ...

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.

The heart's valves are asymmetrical. Mechanical heart valves, are symmetrical. Could an asymmetric design improve blood flow? The heart's valves, which guarantee the unidirectional flow of blood ...

Many valves are used only when necessary to divert ... Patented in 1858 by Henri Gifford, its simple design and efficient operation made previously used forced pumps almost obsolete.

A re-design of the company's 2200-Series mid-size dispense valves yields significant improvements in dispensing and operating performance. Redesign of the one-piece body valves includes the No ...

Mechanical heart valves, however, are symmetric in design – with both flaps of a mitral valve replacement of identical size – and that, Vukicevic and colleagues have found, disrupts the flow ...
