Key Parameters (English) The following are typical technical parameters for the Fisher N562 Gas Regulator. Category Parameter Description / Typical Values Pressure Ratings Maximum Inlet Pressure (P1) Up to 400 psig (28 bar) for standard models. Outlet Pressure (P2) Range Adjustable within a specific range, commonly from 4" w.c. to 60 psig (1 kPa to 4.1 bar). Specific pilots determine the exact range. Capacity Flow Coefficient (Cv) High Cv values. For example, a 2" N562 can have a Cv of approximately 65. Accuracy Excellent accuracy with minimal droop, typically within ±5-10% of the set point. Size & Connections Pipe Size Typically 1/2 inch to 4 inches. End Connections Flanged (ANSI Class 125/150) or Threaded (NPT). Materials Body Material Cast Iron (standard), Ductile Iron, or Aluminum. Internal Trim Stainless Steel, Brass. Safety Features Internal Relief Options Monitor Relief Regulator, Slam-Shut Device, or Spring-Loaded Relief Valve. Environment Operating Temperature Standard for outdoor gas service (e.g., -20°F to 150°F / -29°C to 66°C).
