(1) 轭架套管 – 铝青铜轭架套管最大程度减少操作扭矩。较大通径的截止阀配置针形轴承类型的止推轴承。
(1) Yoke Sleeve – aluminum-bronze yoke sleeve minimizes operating torque. Larger sizes have needle bearing type thrust bearings.

(2) 阀杆 – 精密底面阀杆配置倒置T形头，使得阀杆与楔体连接更加稳定可靠。
(2) Stem – precision-ground stem has upset tee-head for reliable stem/wedge connection.

(3) 压力密封 – 结构简单，分段扣环，镀银低碳钢垫圈，有助于拆卸和最大限度的阀帽密封。
(3) Pressure Seal – uncomplicated design has segmented retaining ring and mild steel silver plated gasket to aid disassembly and provide maximum bonnet seal.

(4) 硬化的阀座表面 – 阀瓣和阀体地阀座表面都经过表面硬化，最大限度延长使用寿命。
(4) Hardened Seating Surfaces – both disc and body seating surfaces are hard faced for maximum service life.

(5) 阀体 – 流线形流道，最大限度减少压降。对焊、缩喉管或法兰连接端口几种可供选择的连接方式。
(5) Body – streamlined flow path minimizes pressure drop. Butt weld, venturi or flanged ends provide piping alternatives.

(6) 执行机构 – 这些阀门可以配置电动、液动或气动执行机构。DN350以下的标准配置是手动执行机构。
(6) Actuators – valves can be supplied with any type of electric, hydraulic or pneumatic actuator. Standard manual actuators are handwheels through 14".

(7) 轭架 – 完全装配式轭架通过抗震测试，易于维护和安装执行机构。
(7) Yoke – fully fabricated yoke is seismically qualified while offering easy maintenance and actuator mounting.

(8) 压盖 – 两件式，自行调整压盖，不需要配置压簧杆。便于维护的转位式螺栓。
(8) Gland – two piece, self-aligning gland eliminates cocking. Swing out bolting facilitates maintenance.

(9) 螺栓轭架 – 轭架是通过螺栓安装在阀体上。
(9) Bolted Yoke – yoke is bolted to body.

(10) 整体后座– 硬面，使用寿命最长。
(10) Integral Backseat – hardfaced for maximum backseat life.

(11) 阀瓣 – 全程阀体导向，是阀座更加适用于高压应用环境。
(11) Disc – fully body guided for perfect seating in high pressure services.
