结构特征
DESIGN FEATURES
- 不旋转阀杆
不旋转阀杆具有精密的圆度和平直度公差，并且经过抛光达到极高的抛光度
NON-ROTATING STEM
Non-rotating stem has close roundness and straightness tolerances and
is burnished for a superior finish.
- 重型两件式密封盖
填料函盖用于承受由动负载产生的高应力
HEAVY TWO-PIECE GLAND
Packing gland is built to withstand high stresses caused by live-loading.
- 动负载
两套Belleville弹簧在石墨填料上保持最小永久性的4000 psi (275 bar) 应力。动负载在不需要维护情况下，保持长期的紧密度。螺栓扭矩控制全部的弹簧负载。
LIVE-LOADING
Two sets of Belleville springs maintain a minimum permanent stress of
4000 psi (275 bar) on graphite packing. Live-loading keeps packing tight
for long periods of time without maintenance. Bolt torques control total
spring load.
- 双填料和无泄漏
一个套环和无泄漏管道用于探测或泄漏拆卸，即便要，也要配置下部密封圈组合（可选择的）
DOUBLE PACKING AND LEAK-OFF
A lantern ring and leak-off pipe provide for detection or removal of
leakage, if any, from lower packing set (optional).
- 又短又窄的填料腔
密封有效性随着整个填料长度的缩短而有所改善。腔壁经过抛光，具有极高的抛光度。
SHORT AND NARROW PACKING CHAMBER
Sealing effectiveness improves as overall packing length shortens. Chamber
wall is burnished to a superior finish.
