Kelebihan Teknikal Kritikal
-
High-Capacity Flow Design: Through the application of aerodynamic and hydrodynamic design principles, the EHAT achieves 30% to 40% higher capacity than conventional valves of comparable size. This allows for smaller valve bodies to handle high-volume high-pressure flows.
-
Balanced Plug Stability: The balanced plug architecture equalizes process pressure across the trim. This drastically reduces the actuator thrust required to modulate the valve, allowing for smoother, high-precision control even at extreme pressure differentials.
-
Panduan Sangkar Lubang Gerudi Lasak: Sangkar lubang gerudi standard memberikan kekuatan mekanikal yang unggul dan ketahanan terhadap getaran. The plug is continuously supported throughout its stroke, protecting the valve from the mechanical stresses inherent in severe service.
-
High-Temperature Shutoff: For thermal extremes, the EHAT can be equipped with metal C-seals or Bore Seals. These permit Class V shutoff at temperatures up to 593°C (1100°F), ensuring reliable performance in high-temperature steam and hydrocarbon isolation.
-
Intermediate Pressure Ratings: With buttwelding end connections and non-destructive testing, the EHAT can conform to ASME Intermediate Special Ratings. This allows for safe operation at pressure/temperature levels that exceed standard Class 2500 ratings.
-
Precise Low-Flow Control: For applications requiring modulation of very low flow rates, the EHAT is available with Micro-Form or Micro-Flute valve plugs, providing excellent rangeability and protecting against “wiredrawing” erosion at small openings.
