Do stop valves have the function of regulating pressure? ?
Thread Content
Can a globe valve control pressure by adjusting its opening degree? ? It’s possible to control the flow rate, but it’s not clear whether pressure can be controlled as well. Please, experts and specialists, explain this to me
It has some effect as well, by reducing pressure through throttling, but it is neither accurate nor stable
Regarding pressure regulation and pressure reduction devices, I believe that components such as valves function as resistance elements; when the valve is opened to a small degree, its cross-sectional area is small, resulting in a higher resistance coefficient that serves to reduce pressure. The original purpose of a shut-off valve is to shut off and seal, so there is no proportional relationship between the valve’s opening degree and its resistance characteristics; fine adjustments are necessary when regulating pressure.
Can’t a stop valve control pressure by adjusting its opening size? The only option is to throttle the flow; if pressure is to be controlled, it means that the valve is open to a very small degree, which affects the flow rate of the medium and may result in it not meeting the requirements of the process. My personal understanding.
I think it’s also for regulating flow; if the pressure changes, it will affect the operation of the process
I don’t think it’s possible; the speed and accuracy seem insufficient
It is best not to use it in this way, as it is difficult to achieve precise pressure control, and the valve can be easily damaged at low opening degrees.
