Specifications: Valve Size: 3" to 30" (DN 80 to DN 750) Pressure Class: ANSI 150 / PN 16 End Connections: Wafer, Lugged, Double Flanged Temperature Range: -29° to 200°C (-20° to 400°F) [Highly dependent on liner material] Performance & Flow Characteristics: Shut-Off Class: ANSI Class VI (Bubble-tight) Flow Characteristic: Approximately Equal Percentage Flow Coefficient (Cv): Very high Cv due to full-port design. Specific values depend on valve size. Pressure-Temperature Rating: Rated for full ANSI 150 pressure across its temperature range when equipped with a reinforced PTFE liner. Materials of Construction: Body: Ductile Iron (standard), Carbon Steel, Stainless Steel. Disc: 316 Stainless Steel (standard), with optional hard coatings like Stellite or Chrome Oxide for extreme abrasion resistance. Shaft: 17-4PH Stainless Steel (standard) Liner (Seat) Materials: Reinforced PTFE (RPTFE): Standard for most corrosive and abrasive services. Ultra-High Molecular Weight Polyethylene (UHMW-PE): Excellent for highly abrasive slurries. Other Elastomers: Available for specific chemical compatibility. Actuator & Accessories: Actuator Types: Pneumatic: Spring-and-Diaphragm Actuators (for modulating control), Piston Actuators (for on/off or high-torque modulating). Electric: Electric Motor Actuators. Positioner: A Fisher FIELDVUE™ DVC or other digital positioner is recommended for precise modulating control, diagnostics, and providing the necessary force for the cam-action mechanism. Accessories: Limit switches, solenoid valves, filter regulators, etc.
