Technical Parameters Category Parameter Specification / Description General Model 1301F-3 Type Direct-Operated Pressure Reducing Regulator Pressure Ratings Maximum Inlet Pressure (P1) 5 psig (0.34 bar) Outlet Pressure Range (P2) Defined by the "-3" spring. This typically indicates a specific, low outlet pressure range, commonly around 3" to 14" WC (0.75 to 3.5 kPa). The exact range must be confirmed from Fisher's spring rate tables. Pressure Rating 125 psig (8.6 bar) Body Rating. Flow & Capacity Flow Capacity (Cv) Very Low (approx. 0.02 to 0.04), designed for small burners and pilots. End Connections Typically 1/2" NPT (Internal Pipe Thread). The "-3" may specify this size. Materials & Environment Body Material Aluminum Internal Parts Stainless Steel, Brass Diaphragm Material Neoprene, fabric reinforced. Ambient Temperature Standard: -20°F to 150°F (-29°C to 66°C)
