Technical Specifications Category Specification Model Type 1301F-N4 Type Self-Operated Pressure Reducing Regulator Function To reduce a higher, variable inlet pressure to a stable, lower outlet pressure. Power Source Self-Operated (Uses energy from the process fluid) Body Style Globe Valve Body End Connections Flanged (typical for "F" designation, e.g., ANSI Class 125 or 150). Outlet Pressure Range Defined by the "N4" configuration. This is a field-adjustable range. A typical range for an "N4" spring could be 4 to 7 psig or a similar low-pressure span. The exact range must be confirmed from factory data sheets. Maximum Inlet Pressure Typically up to 400 psig (28 bar) for standard bodies. Flow Coefficient (Cv) Determined by the orifice size. Temperature Range Standard with Buna-N diaphragm: -20°F to +180°F (-29°C to +82°C). Materials of Construction Body: Cast Iron (standard). Trim (Plug/Seat): Stainless Steel (standard). Diaphragm: Buna-N (standard).
