Ball Valve with Actuator — Pneumatic 3-Piece 316, ISO 5211 Direct Mount, 1000 WOG (V-3AM)

產品說明

This is a ball valve with actuator — a 3-piece stainless steel valve with a pneumatic actuator mounted directly on it — built to solve the headache of servicing welded or threaded automated lines. By removing the body bolts, the central valve section (with the actuator still attached) can be removed or swung out for inspection. That matters most where seals wear out from high cycle rates, or where a line has to be opened and put back the same shift.

The valve is a 3-piece full port stainless steel ball valve with an ISO 5211 mounting pad, driven by a rack-and-pinion aluminum alloy pneumatic actuator in Double Acting (DA) or Spring Return (SR) versions. The ISO 5211 pad is part of the valve body, so the actuator bolts straight down onto it — there is no separate bracket and coupling kit to source and align. 316 stainless steel is in stock; 304 is made to order.

Why a 3-Piece Body Is Right for a Ball Valve with Actuator

• 最低維護成本： 無需拆卸執行器，也無需將組件從管路中切除，即可更換密封件。.
• 高循環耐久性： 自動化生產線的啟停頻率遠高於手動生產線——可維修的機體結構，避免了這項成本演變成更換成本。.
• 無需加熱執行器即可進行焊接： 若管段兩端設有焊接端，可先將管體焊接至管線中，再安裝執行器，藉此保護氣動元件免受高溫影響。.
• 防爆閥桿 以及閥體部分的活載式 PTFE 閥座。.

應用領域

• Chemical and petrochemical processing: transfer, dosing and reactor feed lines carrying acids, alkalis and solvents — lines that have to be opened and closed from a control room rather than by hand.
• Chemical injection on oil and gas surface facilities: corrosion inhibitor, biocide and demulsifier injection points, often at unmanned sites. A spring return actuator drives the valve to its safe position when the air supply is lost.
• 水與廢水處理： coagulant, polymer and caustic soda dosing manifolds, where the dose rate follows water quality and the seats need cleaning on a schedule.
• Pulp and paper: isolation on chlorine dioxide bleaching and caustic lines, where a fast quarter-turn shut-off is part of the safety case.
• Plant utilities: low-pressure steam, condensate, cooling water, compressed air and nitrogen isolation, within the -20 °C to +180 °C body rating.
• Tank farms and loading stations: solvent, acid and alkali storage lines, interlocked with level switches so the valve closes on high level.

常見問題

Does the ball valve come with the actuator already fitted? Yes. The actuator is mounted on the valve at our factory and the two ship together as one unit, so there is no bracket or coupling to source and align on your side. Tell us DA or SR and the end connection you need when you request a quote.

雙作用（DA）或彈簧復位（SR）——我該選擇哪一種？ DA 型執行器利用氣壓來開啟和關閉閥門。SR 型執行器則在氣源中斷時，利用彈簧將閥門驅動至預設的失效安全位置（開啟或關閉）。若管線必須具備失效安全功能，請選用 SR 型；若為一般開關操作，則選用 DA 型。.

我可以在不將閥門從管線中切除的情況下更換閥座嗎？ 是的。拆下殼體螺栓後，中央段便會連同仍安裝在上的執行器一起向外擺動——此時可直接在原位對閥座和密封件進行維護，隨後將殼體重新組裝。.

執行器需要什麼樣的氣源？ 4 至 8 巴（約 58 至 116 psi）的潔淨、乾燥壓縮空氣。.

ISO 5211 代表什麼意思？ ISO 5211 is the standard for actuator mounting pads. The valve carries an F03–F10 pad depending on size (the size-to-pad chart is in the dimension PDFs at the top of this page), so the actuator mounts directly — no bracket — and can be swapped for another ISO 5211 actuator later.

有哪些端部連接方式可供選擇？ PT、NPT 和 PF 規格的螺紋端頭——均有現貨——此外還有套管焊接和對焊規格。關於符合 JIS 標準的對焊自動閥，請參閱我們的 動力驅動對焊球閥 頁面。.

其溫度額定值為何？ The valve body is rated -20 °C to +180 °C (-4 °F to +356 °F), limited by the PTFE seats. The actuator is rated -20 °C to +80 °C, so the combination is limited by whichever part is reached first — tell us your service temperature when you request a quote and we will confirm it.
