(1) 执行机构 – 这些阀门可以配置打击手轮，手动齿轮装置，电动执行机构、液动或气动执行机构。
(1) Actuation – can be supplied with a hammerblow handwheel, manual gear set, electric motor operator, pneumatic or hydraulic cylinder operator.

(2) 阀杆 – 精密底面不锈钢阀杆，最大限度减少操作期间的填料摩擦力。
(2) Stem – stainless steel stem is precision ground for minimal packing friction during operation.

(3) 阀杆导向装置 – 作为阀杆的反旋转装置。
(3) Stem Guide – acts as anti-rotating device for the stem.

(4) 后座 – 整体硬面阀帽后座。
(4) Backseat – integral hardfaced bonnet backseat.

(5) 阀体 – 流线形流道具有很高的流量系数，可以最大限度减少通过系统的压降。
(5) Body – streamlined
flow path demonstrating high Cv factors which minimize pressure drop across a given system.

低压降 = 低操作成本
Low Pressure Drop = Low Operating Cost

(6) 轭架 – 设计符合抗震要求，完全装配式轭架具有装卸容易的特点，执行机构的安装也简便易行。
(6) Yoke – designed to withstand seismic activities, the fully fabricated yoke features hassle – free assembly / disassembly of topworks and simple actuator mounting.

(7) 压盖 – 两件式自行调整压盖及压盖法兰，在调整填料时，不需要压簧杆。
(7) Gland – two piece self-aligning gland and gland
flange eliminates cocking if packing adjustment is required.

(8) 压力密封结构 – 由垫圈，止推环和简易的分段扣环构成，确保最大限度的阀帽密封。*
(8) Pressure Seal Design – consists of a gasket, thrust ring and uncomplicated segmented retaining rings to ensure maximum bonnet seal.*

(9) 导向系统 – 包括一个两件式阀瓣总成和硬面阀体导向装置。这个阀瓣总成在阀门全行程中保持与导向装置的接触。
(9) Guiding System – includes a two-piece disc assembly and hardfaced body guides. The disc assembly maintains contact with the guides through the full valve stroke.

阀座表面 – 阀瓣和阀体阀座表面经过硬面处理，使用寿命更长。
Seating Surface – the disc and body seating surfaces are hardfaced for extended service.
