FISHER 2625-12
Technical Specifications
Category Specification
Model Type 2625-12
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
Orifice Size Defined by the "-12" code, which corresponds to a specific diameter (e.g., 1/2 inch or similar).
End Connections Screwed (NPT) standard.
Outlet Pressure Range Defined by the "-12" configuration. This is a field-adjustable range, but the spring is selected for a specific span. Example ranges could be 5-25 psig or 10-60 psig. 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 "-12" orifice size. This value is critical for sizing the valve for the application's flow rate.
Temperature Range Standard with Buna-N diaphragm: -20°F to +180°F (-29°C to +82°C).
Materials of Construction Body: Cast Iron (standard), Ductile Iron, Brass.
Trim (Plug/Seat): Stainless Steel (standard).
Diaphragm: Buna-N (standard).
