How to vent a self-regulating valve
Thread Content
I would like to ask how to vent air from the pressure lead to the diaphragm in a self-acting control valve, and whether venting is necessary. How to handle high-temperature media?
This doesn’t require exhaust; it’s just a pressure signal. It is recommended to watch principle animation online.
If the measurement is taken in the gas phase, there is no need to vent; but for liquid-phase measurements, how can timely pressure transmission be ensured without venting?
For applications requiring gas/liquid installation, it’s best to read the instructions and understand the principle behind it – that’s what really matters.
