Technical Parameters Parameter Value / Description Fisher Model Number 47B9380X022 Type Pilot-Operated Pressure Regulator (Pilot) Primary Function Acts as a control pilot for a main valve or as a standalone regulator. Pilot Supply Source Typically tapped from upstream pressure or an external gas supply. Body Material Aluminum Trim Materials Standard corrosion-resistant materials (e.g., stainless steel & elastomers). Pressure Rating Typically 1440 psig (100 bar) or similar high pressure. Outlet Pressure Range (P2) Determined by the internal spring. The "X022" suffix likely specifies a particular range. Common 47B series ranges: 5-250 psig, 20-500 psig, etc. Must be confirmed from order records. Inlet Pressure (P1) Up to the pressure rating (e.g., 1440 psig). Connections Typically 1/4" or 1/2" NPT Female Diaphragm Material Typically Nylon-coated fabric or Viton (FKM).
