Specifications: Valve Size: 1/2" to 24" (DN 15 to DN 600) Pressure Class: ANSI 150, 300, 600; PN 10, 16, 25, 40 End Connections: Flanged (RF, RTJ), Wafer, Butt-weld, Screwed Temperature Range (Standard): -29° to 200°C (-20° to 400°F) [Dependent on seat material] Temperature Range (Extended): Available with special seals and materials for cryogenic or high-temperature services. Flow & Performance Characteristics: Flow Characteristic: Approximately Equal Percentage (inherent) Rangeability: Typically 100:1 to 200:1 Flow Coefficient (Cv): Very high Cv values for a given valve size. Specific values are determined by size and V-notch angle. Shut-Off Class: ANSI Class VI (Bubble-tight) with soft seats (e.g., PTFE, RPTFE). Metal seats are available for higher temperatures but with lower leakage class. V-Notch Angles: Common options include 15°, 30°, 45°, 60°, 75°, and 90°. A smaller angle provides finer control at low flows, while a larger angle provides higher capacity.
