Technical Parameters Parameter Specification Model Fisher 3025C Type Pilot-Operated Pressure Reducing Regulator Body Materials Ductile Iron (Standard), Cast Iron, Carbon Steel End Connections Flanged (ANSI Class 150, 300, 600); Butt-Weld Size Range 2" to 8" (DN 50 to DN 200) Maximum Inlet Pressure (P1) Up to 1440 psig (99 bar) for ANSI 600 models. Outlet Pressure Range (P2) Depends on the pilot spring. Wide range available, from a few psig up to 400+ psig. Temperature Range -20°F to 150°F (-29°C to 66°C) with standard Buna-N diaphragms. Flow Capacity (Cv) Very high. Example (4" Size): Cv ~ 240 Accuracy (Droop) Excellent, typically less than 5% of the setpoint due to pilot-operated design. Pilot Options Available in various setpoint ranges and can be equipped with a supplemental loading pilot for more complex control.
