المزايا التقنية الحاسمة
Streamlined Expanded Geometry: The V150E is built with an outlet flange that is one standard line size larger than the inlet. This internal expansion facilitates a smooth transition for the process fluid, effectively managing the increase in volume as pressure drops across the valve.
Enhanced Structural Integrity: The valve body is manufactured as a one-piece casting. By eliminating the bolted joints and gaskets found in two-piece designs, the V150E offers a superior pressure boundary with no potential leak paths, ensuring maximum safety and environmental compliance.
Trim Interchangeability: To simplify maintenance and inventory management, the internal trim components of the V150E are fully interchangeable with the standard Fisher V150, V200, and V300 series B valves. This allows facilities to utilize existing spare parts for the expanded outlet variant.
Heavy-Duty Metal Sealing: Designed for demanding industrial environments, the V150E utilizes a heavy-duty metal seal construction. This ensures a long service life and reliable shutoff even in high-temperature or mildly abrasive services.
Precision Motion Control: The combination of precision-machined parts, a pressure-balanced seal, and low-friction bearings ensures smooth, high-resolution movement of the ball. This minimizes stick-slip and deadband, providing the accurate control necessary for sensitive process loops.
Optimized Flow Characteristic: The V-notch ball is precisely contoured to provide a modified equal percentage flow characteristic. This allows for excellent rangeability and precise throttling at low flow rates while maintaining high capacity at the outlet.
