(1) 轭架套管 –铝青铜轭架套管*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 minimizesoperating torque. Larger sizes have needle bearing type thrustbearings. (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*大限度的阀帽密封。
(3) Pressure Seal– uncomplicated design has segmentedretaining ring and mild steel silver plated gasket to aiddisassembly 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，*大限度延长使用寿命。
(4) Hardened SeatingSurfaces – both disc and bodyseating surfaces are hard faced for maximum service life. (5) 阀体 –流线形流道，*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 ofelectric, hydraulic or pneumatic actuator. Standard manualactuators 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 eliminatescocking. 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*长。
(10) IntegralBackseat – hardfaced formaximum 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 inhigh pressure services. |
