Does py0101 refer to a solenoid valve? What does I/P mean?
A pressure control system includes a valve assembly, a bypass line, and a drain line
This is a pressure control valve assembly, with signal wires connecting to the corresponding pressure gauge points; the control valves are used to regulate the respective pressures. The PO valve serves a protective function – in the event of a loss of supply air to the gauges, the valve opens fully to protect the equipment and pipelines
Positioner, safety barrier – electrical conversion
PY-0101 refers to the electrical valve positioner, while I/P denotes current/pneumatic signal conversion. The electrical valve positioner has two functions: 1. To convert current signals into pneumatic signals ； 2. Achieve accurate positioning of the pneumatic control valve’s position.
"\"Current/pressure signal conversion\" – I’ve learned about it now; before I only knew its function and had a superficial understanding of electrical and instrumentation systems, but now I understand it better. The issue is that pneumatic valves are related to P; do electric valves not have these problems?
I/P are the initial letters in English; the poster should learn more professional English^_^
