Design Features

1. Friction‑free Opening and Closing
This feature thoroughly resolves sealing failure caused by mutual abrasion between sealing faces of conventional valves.

启闭无摩擦。这一功能完全解决了传统阀门因密封面之间相互摩擦而影响密封的问题。
2.Top‑mounted Structure
Valves fitted on pipelines can be inspected and maintained online directly, minimizing equipment shutdown and cutting operating costs.

装式结构。对装在管道上的阀门可直接在线检查与维修，能有效减少装置停车，降低成本。
3.Single‑seat Design
It rules out safety hazards triggered by abnormal pressure rise of medium trapped inside the valve cavity.

单阀座设计。消除了阀门中腔介质因异常升压而影响使用安全的问题。
4.Low‑Torque Design
The specially‑designed stem enables easy valve operation merely with a small handwheel.

低扭矩设计。特殊结构设计的阀杆，只需配一个小手轮阀门就能轻松启闭。
5.Wedge‑type Sealing Structure
Mechanical force from the stem pushes the ball firmly against the seat. Consequently, sealing performance remains stable regardless of pipeline pressure difference under all working conditions.

楔形密封结构。阀门是靠阀杆提供的机械力，将球楔压到阀座上而密封，使阀门的密封性不受管线压差变化的影响，在各种工况下密封性能都有可靠保证。
6.Self‑cleaning Sealing Face
When the ball departs from the seat, process fluid flows 360° evenly across the sealing surface. This prevents localized erosion from high‑velocity fluid and flushes deposits away to realize self‑cleaning.

密封面的自清洁结构。当球体倾离阀座时，管线中的流体沿球体密封面成 360° 均匀通过，不仅消除了高速流体对阀座局部的冲刷，也冲走了密封面上的聚积物，达到自清洁的目的。
