Key Parameters Category Parameter Description / Typical Values Pressure Ratings Inlet Pressure (P1) Up to 4000 psig (275 bar). Outlet Pressure (P2) Range Varies with size and spring/dome load. Typically from 15 to 1500 psig (1 to 103 bar). Consult sizing tables. Max. Shutoff Pressure Up to the maximum inlet pressure rating. Size & Connections Orifice Size Common sizes: 1/2 inch, 3/4 inch, 1 inch, 1-1/2 inch, 2 inch. End Connections NPT (Standard), Flanged (ANSI Class 150, 300, 600, 900, etc.), or SW (Socket Weld). Flow & Performance Flow Coefficient (Cv) High Cv values, e.g., up to 45 Cv for a 2" orifice. Accuracy & Droop Excellent accuracy with minimal droop due to the pilot-operated design. Materials Body Materials Carbon Steel (Standard), Stainless Steel (316). Trim Materials Stainless Steel, etc. Pilot Options Control Type Spring-Loaded Pilot: Setpoint is adjusted by a spring. Dome-Loaded Pilot: Setpoint is controlled by applying an external air or gas signal to the dome, allowing for remote control. Environment Operating Temperature Standard: -20°F to +150°F (-29°C to +66°C). Extended temperature ranges available with optional elastomers.
