Ưu điểm kỹ thuật quan trọng
Balanced Plug Efficiency: The ET uses a balanced valve plug design, which equalizes the pressure across the trim. This significantly reduces the actuator force required to operate the valve, allowing for precise modulation with smaller, more economical pneumatic or electric actuators even at high pressure drops.
High-Integrity Sealing: Excellent shutoff is maintained through a sophisticated seal ring system. A backup ring or spring-loading mechanism forces the valve plug seal ring against the cage, while the seat construction protects a PTFE disk between a metal seat and retainer. This combination allows the ET to achieve stringent Class V or VI shutoff ratings.
Hệ thống dẫn hướng lồng chắc chắn: Nút van được đỡ liên tục bởi một lồng chịu lực cao. This design provides exceptional plug stability, which is critical for reducing vibration and mechanical noise in high-velocity or high-pressure drop applications
Advanced Thermal Management: Designed for high process temperatures, the ET maintains its structural and sealing integrity where standard valves might fail. Its materials and seal designs are optimized for thermal expansion and consistent performance across a broad temperature range.
Fugitive Emission Control: Compatible with ENVIRO-SEAL™ packing systems, the ET helps plants comply with environmental regulations. These live-loaded PTFE or Graphite ULF systems provide a superior stem seal that reduces process fluid loss and extends maintenance intervals.
NACE and International Standards: The ET series is available in dimensions specified by EN/DIN standards and can be configured with metallurgy that meets NACE MR0175 / ISO 15156 and MR0103 for protection against stress-corrosion cracking in sour environments.
