Can a needle valve regulate pressure?
Thread Content
Can needle valves be used to replace globe valves for regulating pressure in hydraulic oil pipelines with small diameters?
In principle, the regulating performance of a needle valve is better than that of a globe valve
Pin valves can regulate pressure; it is important to note whether the flow characteristics meet the requirements.
After we adjusted it to 6 kilograms, the pressure slowly returned to 4 kilograms. What’s the problem?
Our technical expertise suggests that the pressure becomes harder to control as it builds up, so it will gradually start to drop back
Because inside your needle valve, there is just a throttle valve disc. It definitely cannot be used as a control valve~
What is the inlet pressure, the flow rate, and the valve opening degree? At the 6 kg and 4 kg instantaneous values
This small needle valve allows only a very slight degree of opening.
Dear friends from the valve factory, please upload the image and help analyze it. Thank you! Is there such a small shut-off valve?
