What is the manual regulating valve with low resistance?
Thread Content
If the life can be longer, the flow rate can be adjusted, and it does not need to be linear. Thanks in advance!
Manual adjustment valves include stop valves and butterfly valves. The one with smaller resistance is the butterfly valve.
Agree with the opinion above, just choose a manual butterfly valve that can lock itself! ! Little resistance
The V-shaped ball valve has higher adjustment performance or if the cut-off valve adjustment accuracy is not high and the flow resistance is small, use a butterfly valve.
It depends on what the medium is, what the pipe diameter is, what the temperature and pressure are, and then you can make a specific selection.
The medium is water, normal temperature, pressure
Use a manual butterfly valve with self-locking function and scale display. Although the adjustment performance of the stop valve is better than that of the butterfly valve, the flow resistance is large. And the cost of a large diameter like yours is high.
