(1) 双瓣轻型结构，阀座密封和运行更加有效
(1) Dual plate lightweight design for efficient seating and operation

(2) 长臂弹簧作用，使得阀瓣能够在不摩擦阀座的情况下开启和关闭
(2) Long-leg spring action allows plates to open and close without seat scrubbing.

(3) 弹簧独立作用关闭阀瓣。(DN150及以上)
(3) Spring action closes plates independently. (6" and larger)

(4) 铰链支撑套管减小摩擦，并将通过独立阀瓣中止时的水锤现象降到最小程度(更大的通径)。
(4) Hinge support sleeve reduces friction and minimizes water hammer through independent plate suspension (on larger sizes).
