High-Performance Butterfly Valve
Double-eccentric high-performance butterfly valve with reinforced PTFE seat for reliable on-off and modulating service.
Inquire NowProduct Overview
The high-performance butterfly valve uses a double-eccentric disc design and reinforced PTFE seat to combine low torque, bi-directional shutoff, and proportional control in one compact body. The double-eccentric geometry lifts the disc off the seat immediately upon opening, minimizing seat wear and extending service life.
Compared with resilient-seated butterfly valves, this design offers higher pressure capability and better resistance to thermal cycling, suitable for service up to PN25 / Class 300.
Key Features
- Double-Eccentric Geometry: Disc lifts off seat on opening, eliminating seat wear
- Reinforced PTFE Seat: R-PTFE seat withstands higher pressure and temperature
- Bi-Directional Shutoff: Zero-leakage in either flow direction
- Compact & Lightweight: Saves weight and installation space vs. gate valves
- ISO 5211 Mounting: Standardized mounting flange for any actuator type
Technical Highlights
Typical Applications
Water distribution, HVAC, light chemical, food processing, pulp & paper, shipbuilding, power plant auxiliary.
产品概述
高性能蝶阀采用双偏心蝶板设计和加强型PTFE阀座，集低扭矩、双向密封和比例调节于一体。开启瞬间蝶板脱离阀座，最大限度减少阀座磨损，延长使用寿命。
相比弹性密封蝶阀，本设计承压能力更高、耐温循环性能更好，适合PN25/Class 300及以下工况。
核心特点
- 双偏心结构： 开启瞬间蝶板脱离阀座，避免阀座磨损
- 加强PTFE阀座： R-PTFE阀座可承受更高压力和温度
- 双向密封： 两个流向均能实现零泄漏
- 紧凑轻便： 相比闸阀重量轻、安装空间小
- ISO 5211安装： 标准化安装面，适配任意执行器
