Can the cut-off valve adjust the flow?

Cut-off valve can adjust the flow, but it is much worse than regulating valve.

In practice, the cut-off valve can also adjust the pressure or flow, but it is a coarse adjustment, not a near adjustment. Stop valve and regulating valve should not be confused, and those that meet the requirements of coarse adjustment can be used in individual places.

Cut-off valve can adjust the flow, but it is coarse, mainly used in pump outlet, before and after regulating valve, heat exchanger cooling water and other parts. Needle valve can be used for precise adjustment, but its diameter is relatively small.

Gate valves are generally used to cut off, not to adjust the flow.

The regulating valve can automatically adjust the flow, but it is expensive. A regulator can buy a mid-range car like Roewe and Buick, and a large-caliber car is more expensive. Whether to adopt regulating valve or manual valve depends on the comprehensive choice of process requirements and economic angle.

When selecting valves, we must pay attention to this point: stop valves can only control the flow roughly, and to control the flow accurately, we must use regulating valves or valves with dials, so as to control the flow more accurately.
