I have a question regarding a pressure gauge and a control valve
Thread Content
What is the function of this pressure gauge? What is the function of the middle part at the top of the control valve? Thank you for your guidance, expert.
Is this pressure the pressure of the instrument air supply, before pressure reduction? That exhaust port is the spring chamber~
The middle part at the top of the control valve is the section where the control valve receives signals and carries out actions
The function of the control valve is normally air-operated, right? The central structure is equipped with a top-mounted manual actuator
The photos are incomplete; it’s not possible to tell where the pressure is coming from
The pressure gauge is supposed to measure the pressure in the pipeline, while the one on the control valve is likely a spare handwheel

The pressure gauge should be used to measure differential pressure
Just like ordinary pressure pipelines, with fluid coming in through a single tube, how can differential pressure be measured?
