Key Parameters Category Parameter Description / Typical Values Pressure Ratings Maximum Inlet Pressure (P1) Up to 1440 psig (100 bar). Outlet Pressure (P2) Range Configurable via pilot selection. Designed for high outlet pressures, often ranging from hundreds to over a thousand psig. Capacity Flow Coefficient (Cv) Extremely high Cv values. For example, a 6" P700 can have a Cv of over 1500. Accuracy & Droop Excellent, typically within ±1-2% of the set point due to the pilot-operated design. Size & Connections Pipe Size 2 inches (DN50) to 8 inches (DN200). End Connections Flanged (ANSI Class 600, 900, 1500). Materials Body Material Forged Steel (standard for high pressure). Trim Materials Stainless Steel. Pilot & Safety Pilot Types Reducing Pilot, Monitor Pilot, Dome-Loaded Pilot. Safety System Almost always installed upstream with a Fisher PSL or PSS Slam-Shut Valve for critical overpressure protection. Environment Operating Temperature Standard: -20°F to +150°F (-29°C to +66°C).
