Critical Technical Advantages
-
Compact Wafer Design: The V200 features a flangeless, wafer-style body that is held in place by line flange bolts. This design significantly reduces the weight and overall length of the valve compared to flanged versions, making it easier to install in tight piping configurations.
-
Precise Throttling Performance: The V-notch ball is specifically contoured to provide a modified equal percentage flow characteristic. This allows for high-resolution control and a broad rangeability, ensuring the valve can handle process disturbances with minimal variability.
-
Shearing Action for Slurries: The V-notch design creates a natural shearing action as the ball closes against the seal. This makes the V200 exceptionally effective at cutting through fibrous slurries or particles that would typically clog or jam standard globe valves.
-
Flexible Sealing Options: The valve utilizes a pressure-balanced seal design that ensures smooth operation and tight shutoff. The ball seals are accessible at the valve inlet, allowing for inspection and replacement without the need to disassemble the entire valve or remove the actuator.
-
Structural Integrity: Despite its compact profile, the V200 is engineered with a one-piece body that eliminates the leak paths associated with multi-piece bolted designs. This enhances the safety and reliability of the pressure boundary.
-
Fugitive Emission Control: Compatible with the ENVIRO-SEAL live-loaded packing system, the V200 can maintain a superior stem seal for long periods. This reduces maintenance requirements and ensures compliance with strict environmental regulations.
