The SPTVL Transfer Valve suited for corrosive processes such as etch or CVD, the technology of L-motion of the gate by a single-shaft pneumatic actuator. In a L-motion, the gate is moved vertically into close position – without any contact to the valve body – and in the final movement it is pushed horizontally to the gate seat, with the seal touching the gate seat with a fixed force, related to the connected air pressure.SPTVL傳輸閥適用于腐蝕工藝，如蝕刻或 CVD，通過單軸氣動執(zhí)行器對閘門進行 L 型運動的技術(shù)。在 L 型運動中，閘門垂直移動到接近位置 - 不與閥體有任何接觸 - 在最后的運動中，它被水平推到閘閥座上，密封件以與連接的氣壓相關的固定力接觸閘閥座。
To minimize particle generation and activation, the gates are fitted with vulcanized seals. This is a highly reliable and more durable sealing solution then a standard O-ring sealing, although standard O-ring sealing is available as an option. The shaft feedthrough is sealed with highly durable metal welded bellows.為了最大限度地減少顆粒的產(chǎn)生和生成，閘門配有閥板配備了硫化密封件。這是一種高度可靠且更耐用的密封解決方案，而不是標準 O 形圈密封，盡管標準 O 形圈密封可作為選項提供。軸饋入裝置采用高度耐用的金屬焊接波紋管密封。
In case of power failure, the SPTVL can be mechanically locked in close and open position.在停電的情況下，SPTVL 可以機械鎖定在關閉和打開位置。
Already installed in hundreds of demanding applications in various semiconductor, Solar and Industry production processes, the SPTVL series has proven its outstanding reliability. With a robust design as well as reduced and easy maintenance, the SPTVL series convinces in all aspects.SPTVL 系列已經(jīng)安裝在各種半導體、太陽能和工業(yè)生產(chǎn)過程中的數(shù)百個要求苛刻的應用中，證明了其出色的可靠性。憑借堅固的設計以及減少和易于維護，SPTVL 系列在各個方面都令人信服。
The SPTVL Transfer Valve is always tailored to customer specifications. Nevertheless, four basic design types are predefined: two valve types with different rear side openings and two insert types with inside or outside chamber valve seat.SPTVL 傳輸閥始終根據(jù)客戶規(guī)格量身定制。盡管如此，仍預定義了四種基本設計類型：兩種具有不同后側(cè)開口的閥類型和兩種帶內(nèi)腔或外腔閥座的插入類型。
The valve body material options are aluminum, hard anodized, nickel-plated or stainless steel. Gate and bonnet seals are in FKM or FFKM. Other sealing materials are available on request.閥體材料選項為鋁、硬質(zhì)陽極氧化、鍍鎳或不銹鋼。閘門和閥蓋密封件為 FKM 或 FFKM。可根據(jù)要求提供其他密封材料。
