(1) 明杆 - 易于观察开启-关闭状态。
(1) Rising Stem – easily visible open-close indication.

(2) 润滑油附件 - 轭架套管配置润滑油附件，降低磨损和操作扭矩。
(2) Grease Fittings – yokesleeves equipped with fittings to minimize wear and operating torque.

(3) 旋启式螺栓 - 使得维护和填料更换更加简便易行。
(3) Swing Bolts – facilitate easier maintenance and packing replacement.

(4) 填料函 - 可配置备选灯笼环和润滑油注射器。
(4) Stuffing Box – optional lantern rings and grease injectors are available.

(5) 后座 - 经过精密加工的阀盖阀杆衬套实现后座阀杆密封。
(5) Backseat – machined bonnet stem bushing provides back-up stem seal.

(6) 阀盖连接 - ANSI压力等级不同，连接结构也有所不同。
(6) Bonnet Joint – joint design varies with ANSI class rating.

(7) 阀体 - 全流道(全端口)，重型阀体，符合API 600标准的壁厚，最大限度延长使用寿命。可配置用于旁路阀或排泄阀的轮毂。
(7) Body – full ported, heavy duty body with API 600 wall thickness for maximum service life. Provided with bosses for optional by-passes or drains.

(8) 阀座环 - 分离式重型、全流道(全端口)环，易于维护。
(8) Seat Rings – separate heavy duty, full ported rings for easy maintenance.

(9) 手轮 - 易于操作的大手轮。也可配置齿轮操作机构，马达执行机构或缸体执行机构，以满足更高的应用环境要求。
(9) Handwheel – large handwheels for easy operation. Also available with gearing, motor actuators or cylinder actuators for more difficult services.

(10) 轭架套管 - 配置含镍抗腐蚀剂球墨铸铁或铝青铜材料，降低操作扭矩。
(10) Yokesleeves – furnished in ductile Ni-resist or aluminum-bronze to reduce operating torque.

(11) 压盖 - 两件式压盖/压盖法兰，自行对准调节，防止由于压盖翘起而造成阀杆损坏。
(11) Gland – two-piece gland/gland flange is self-aligning to eliminate stem damage from cocked gland.

(12) 阀杆 - 所有美国太平洋楔形闸板闸阀配置倒T形头锻造阀杆。通过锻造T形头，这种阀杆在阀杆-楔形闸板连接处更加结实牢固。这种结构也使得楔形闸板能够自行对准调节，消除了由于阀杆弯曲而堵塞楔形闸板的可能性。
(12) Stem – all Pacific wedge gate valves are provided with upset forged T-head stems. By forging the T-head, the stem at the stem-wedge connection is stregthened. This design also allows the wedge to self-align, eliminating the possibility of a bent stem jamming the wedge.

(13) 楔形闸板 - 重型、全导向楔形结构，精密配合阀体阀座，实现最有效的关闭。可提供H.I.S.(高度整体性关闭)结构的闸板。
(13) Wedge – heavy pattern, fully guided wedge precision fitted to body seats for maximum shutoff. Available in H.I.S. design.

(14) 连接端口 - 可提供两种法兰联接端口，凸面光滑表面或环形连接。
(14) End Connections – flanged end options are raised face smooth finish or ring type joint.

软阀座T形阀座环
SOFT SEATED "T" TRIM SEAT RING

　　所有闸阀都可以配置备选的聚四氟乙烯(PTFE)阀座环。这种模铸聚四氟乙烯环粘合在阀座表面的阀座环槽内，最大限度延长使用寿命。这种结构对于要求紧密性关闭的低温应用特别适用。
　　All gate valves are available with optional PTFE seat rings. The molded PTFE ring is bonded into a seat ring groove in the face for maximum service life. This design is excellent for lower temperature service where tight shutoff is required.
