Choked vapor flow conditions are very common in relief valves and control valves with very high flows, but can also occur in high velocity flare headers at piping transitions. Choked flow is also ...

Restrictive flow regulators are ideally suited to constant-pressure closed-center circuits and meter-out situations. Experts say they are the only pressure-compensated flow control that can be ...

That means the relationship between the controller output signal versus the control valve flow rate will be changing throughout all the different operational conditions and the loop tuning parameters ...

Slug flow can cause serious problems in the design and operation of two-phase flow systems. Automated control techniques using variable choke-valve sizes offer a new approach to controlling slug flow.

Municipal Authority of Westmoreland County board members last week approved a $9.6 million project to install new equipment ...

Coal particles can build up in the flow control head chute when it is not properly designed. At this plant, the coal buildup falls on the floor when the inspection door is opened.
