Muhim texnik afzalliklar
-
High Capacity Design: Through advanced aerodynamic and hydrodynamic flow-stream contouring, the EHT achieves 30% to 40% higher capacity than conventional globe valves of similar size. This efficiency allows for optimized process control and potentially smaller valve footprint.
-
Balanced Plug for Stable Control: The EHT features a balanced plug architecture that equalizes process pressure across the trim. This significantly reduces the actuator thrust required to move the valve, allowing for smooth, high-precision modulation even at extreme pressure differentials without needing massive actuators.
-
Rugged Drilled-Hole Cage Guiding: Standard drilled-hole cages provide superior mechanical strength and resistance to vibration. This heavy-duty guiding system supports the plug throughout its entire stroke, protecting internal components from the mechanical stresses inherent in high-velocity steam or liquid service.
-
High-Temperature Shutoff: For extreme thermal environments, the EHT can be equipped with metal C-seals or Bore Seals. These specialized seals permit Class V shutoff at temperatures up to 593°C (1100°F), ensuring reliable isolation in high-temperature headers and bypass lines.
-
Intermediate Pressure Ratings: With buttwelding end connections and non-destructive testing, the EHT can conform to ASME Intermediate Special Ratings. This allows the valve to operate safely at pressure and temperature levels that exceed standard Class 2500 ratings.
-
Long Trim Life: Hardened materials for the cage, plug, and seat are standard for all applications. This high wear resistance, combined with the stability provided by the cage guiding, ensures a long service life and reduces maintenance frequency in erosive environments.
