Self-regulating valve pressure issues
Thread Content
As the title suggests: The pressure target set for the instruments in our factory is 7 kilograms, but the maximum range of the pressure gauges on some self-regulating valves is 6 kilograms. I would like to ask those who are more experienced: Do self-regulating valves come equipped with their own pressure reduction devices, or does it depend on the type of valve – some have such devices while others do not? Given this situation, is it necessary to install pressure relief valves on the instrument branch lines in each section? Could everyone discuss whether such a situation has occurred in your factories, and if so, how it was controlled?
Self-regulating valves generally have pressure regulation devices. There is no need to install a pressure regulator on the automatic control valve for instrument air; otherwise, when the pressure of the instrument air fluctuates greatly, the automatic control valve will fail to function properly.
When specifying the control valve, indicate that it should be equipped with an air filter and pressure regulator. Different control valves require different operating pressures, and it is not advisable to use ones without such a filter and regulator
Valves have a specified operating pressure; 7 kilograms represents the total air pressure, and the pressure reducing valve is used to adjust this value
