(1) 軛架套管 –鋁青銅軛架套管*大程度減少操作扭矩。較大通徑的截止閥配置針形軸承類型的止推軸承。
(1) Yoke Sleeve– aluminum-bronze yoke sleeve minimizesoperating torque. Larger sizes have needle bearing type thrustbearings.

(2) 閥桿 – 精密底面閥桿配置倒置T形頭，使得閥桿與楔體連接更加穩定可靠。
(2) Stem – precision-ground stem has upset tee-head for reliable stem/wedge connection.

(3) 壓力密封 –結構簡單，分段扣環，鍍銀低碳鋼墊圈，有助于拆卸和*大限度的閥帽密封。
(3) Pressure Seal– uncomplicated design has segmentedretaining ring and mild steel silver plated gasket to aiddisassembly and provide maximum bonnet seal.

(4) 硬化的閥座表面 – 閥瓣和閥體地閥座表面都經過表面硬化，*大限度延長使用壽命。
(4) Hardened SeatingSurfaces – both disc and bodyseating surfaces are hard faced for maximum service life.

(5) 閥體 –流線形流道，*大限度減少壓降。對焊、縮喉管或法蘭連接端口幾種可供選擇的連接方式。
(5) Body – streamlined flow path minimizes pressure drop. Butt weld, venturi or flanged ends provide piping alternatives.

(6) 執行機構 –這些閥門可以配置電動、液動或氣動執行機構。DN350以下的標準配置是手動執行機構。
(6) Actuators– valves can be supplied with any type ofelectric, hydraulic or pneumatic actuator. Standard manualactuators are handwheels through 14".

(7) 軛架 – 完全裝配式軛架通過抗震測試，易于維護和安裝執行機構。
(7) Yoke – fully fabricated yoke is seismically qualified while offering easy maintenance and actuator mounting.

(8) 壓蓋 – 兩件式，自行調整壓蓋，不需要配置壓簧桿。便于維護的轉位式螺栓。
(8) Gland– two piece, self-aligning gland eliminatescocking. Swing out bolting facilitates maintenance.

(9) 螺栓軛架 – 軛架是通過螺栓安裝在閥體上。
(9) Bolted Yoke– yoke is bolted to body.

(10) 整體后座– 硬面，使用壽命*長。
(10) IntegralBackseat – hardfaced formaximum backseat life.

(11) 閥瓣 – 全程閥體導向，是閥座更加適用于高壓應用環境。
(11) Disc– fully body guided for perfect seating inhigh pressure services.
