Self-acting control valve
Thread Content
May I ask where exactly is the pressure tapping point for a self-acting control valve with internal pressure tapping? Is a pressure tap needed? I only have the external dimension diagram
Pressure tapping pipes are needed, but not in large quantities; something slightly higher than the valve will do, in a 7 shape. As for the location, it depends on whether this valve controls the pressure before or after the valve; there is a difference.
The pressure tapping point for self-acting control valves with internal pressure sensing is usually located inside the valve body, on the side facing the outlet； There are no exposed pressure tapping pipes, but some may be present inside the valve body and others may not; it depends on the specific internal structure.
