(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(wěn)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(huán)，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(jīng)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(zhí)行機構 –這些閥門可以配置電動、液動或氣動執(zhí)行機構。DN350以下的標準配置是手動執(zhí)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(zhí)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(huán)境。
(11) Disc– fully body guided for perfect seating inhigh pressure services.
