August 2021 Choked Flow in Control Valves Choked Flow in Control Valves By Katherine Bartels, Adam Harmon Summary Choked flow in control valves is a subject of serious concern for industrial users.

Watch on Pressure-compensated flow control valves are designed to provide a constant volume flow rate independent of the pressure drop across the valve. By contrast, non-pressure-compensated valves ...

Figure 1: In slow processes (right), a positioner always improves loop performance, but in fast processes (left), particularly if the controller is pneumatic and the process is faster than the ...

Low flow control valves are essential for regulating fluid flow in various industrial processes, such as chemical, pharmaceutical, food and beverage, and water treatment.

Flow management is a really important part of many industries. Being able to precisely control the flow of liquids and gases is crucial for making industrial processes as efficient, safe, and ...

“This addition of the Iris flow valves to our product line is the perfect fit with our other products,” Lorenz Conveying president Peter Lorenz said. “It gives us a new customer base that blends ...

Prodim, Rotork’s agent in Belgium, proposed the use of the CVL-5000 electric control valve actuator as an alternative to the existing actuator on a blending flow control valve in a trial at the Fluxys ...

In this study, we have fabricated and evaluated a flow control valve for oil-hydraulic soft actuators. To install oil-hydraulic actuators on a robot to realize actuation with high-power, there is a ...

1. Flow-to-open cutaway. Control valves equipped with noise-abatement trim, such as a drilled-hole cage or a tortuous path stack, are typically oriented in the flow-to-open direction.

November 13, 2014 - Rotork’s CVA electric control valve actuator technology has successfully delivered an improvement in performance with reduced operating costs for the vital gas blending process on ...
