Can gate valves be used to regulate flow?
Thread Content
Can gate valves be used to regulate flow? Can the performance of a gate valve be used to regulate flow? Some say it’s absolutely prohibited! It’s not a matter of adjustment accuracy, but rather it is determined by its structural characteristics. If the gate is half-open, a vortex will form behind it, causing severe damage to the gate. Has such a situation ever happened? Help!
Such situations do occur. Therefore, in order to avoid severe damage to the gate and the difficulties associated with adjusting its precision, I personally recommend using a globe valve instead of a gate valve, which is a more reasonable choice
It seems that gate valves here are only used for opening and closing. 0 or 1
A gate valve is a on/off valve used for shut-off; it is generally not used for regulating flow.
In terms of application, it is used this way, but in actual production, it is often employed for regulating flow rate. Due to the inherent principle of the valve body, its regulation capability is very poor. Therefore, some install additional control valves for regulation. It’s fine for rough adjustment. Regarding the loss issue, under normal conditions (materials, flow rate, medium, and compliance with valve body requirements), it is still acceptable.
According to the written text, the extract is as follows: Gate valves have low flow resistance but require significant effort to open and close; they are widely used for opening and closing pipelines carrying various types of media. When the valve is partially open, vortices are generated on the back side of the gate, which can lead to erosion and vibration of the gate as well as damage to the valve seat seal surface; repair is difficult. Therefore, gate valves are generally not used for throttling purposes.
Gate valves are not suitable for regulating flow; they serve to shut off flow, and globe valves or butterfly valves can be used for that purpose
