Sanitary Butterfly Valve — Pneumatic Wafer Body, 304 Stainless, Tri-Clamp

產品說明

A 片式氣動蝶閥 in 304 stainless steel (316 to order), sized Ø12.7 to Ø101.6 mm (1/2″ to 4″ tube OD). The valve body is clamped between two ferrules and the disc rotates 90° to open or close. A pneumatic actuator sits on the top platform, bolted through four M6 or M8 holes.

It is short, light and cheaper than a ball valve of the same size — and that is exactly what it is for. Face-to-face runs 66 to 82 mm across the whole range, so it drops into piping that has no room for a ball valve. Full dimensions are on the dimension sheet above.

The PTFE Seat and Your Line Temperature

此閥門的閥座是 PTFE, and it is the seat that sets the working temperature — the 304 stainless body will take far more heat than the seat will.

Tell us the temperature of your line when you enquire — a heated jacket, a hot flush, a wash cycle — and we will confirm the seat suits it.

規格

該選擇哪種致動器：DA 還是 SR？

• 雙作用（DA） — 靠氣壓將其打開，靠氣壓將其關閉。一旦氣壓消失，圓盤便會…… 維持原狀. 請在可接受閥門卡死在某個位置的情況下使用此產品。.
• 彈簧復位 (SR) — 氣壓驅動其朝一個方向移動，彈簧則使其回彈至另一個方向。一旦氣壓喪失，彈簧便會接管作用。此裝置適用於閥門在氣壓喪失時必須停留在已知位置的場合。.

請告知我們閥門必須以何種方式失效，我們將為您報價相應的氣缸。這與我們用於球閥的氣缸系列相同，因此同時使用這兩類產品的工廠只需備一份備件清單。.

歸屬之處

• Water treatment and filtration skids — isolation on reverse-osmosis pretreatment, cooling tower sidestream filtration and clarifier effluent lines, where the valve cycles often and the skid has no space to spare.
• Chemical process lines — the PTFE seat covers the wetted surface of the body, so acids, alkalis and solvents never reach the metal.
• Beverage and brewing transfer lines — the clamp connection lets you lift the whole valve out between batches without unbolting pipework.
• Air handler coils and branch take-offs — chiller, boiler and change-over branch points, where a short wafer body fits what a ball valve will not.
• Heat exchanger branch circuits — isolation and bypass around plate heat exchanger loops, chosen on cost, weight and footprint.
• Compressed air and nitrogen utility lines — high-cycle automatic shut-off on plant branches; double acting and spring return cylinders both in stock.

向我們購買

• 製造商，而非貿易公司。. 這些產品均由我們位於台灣的自有工廠生產，自1999年起便持續製造不鏽鋼閥門。.
• 閥門與執行器均來自同一供應商。. 氣缸是我們的，閥門也是我們的，兩者在出貨前已進行過配對。現場無需再進行任何調整。.
• 歡迎 OEM 合作。. 請將您的草圖寄給我們。.

請告知我們尺寸、材質及其溫度，以及您需要的是 DA 還是 SR。這些資訊已足以讓我們為您報價。.

常見問題

什麼因素會限制這款蝶閥的溫度？

The seat, not the body. The seat is PTFE, and it reaches its limit long before the 304 stainless body does. Tell us the temperature of your line when you enquire and we will confirm whether this valve suits it.

蝶閥是正確的選擇嗎？還是我應該購買球閥呢？

Buy the butterfly valve for tank isolation, large flow and on/off duty, especially at 2″ and above where it is clearly cheaper. Buy a 球閥 if you need a straight unobstructed bore, if the medium carries particles that could wedge against the disc, or a 三通球閥 if you need to divert flow between two lines. We make both and will tell you which one your line needs.

當閥門開啟時，閥芯會留在流道中嗎？

是的。這就是所有蝶閥的運作原理——閥盤會以邊緣朝向流體的方向旋轉，但絕不會離開閥體內孔。若您需要一個通暢無阻的通道，球閥才是您的最佳選擇。.

你們生產哪些尺寸？

Ø12.7 to Ø101.6 mm, which is 1/2″ to 4″ tube OD. Eight sizes, all listed on the dimension sheet above.

我應該訂購哪種執行器——雙作用式還是彈簧復位式？

若在氣源中斷時，碟片可維持原位，則採用雙作用型；若閥門在氣源中斷時必須停留在特定位置，則採用彈簧復位型。請告知您所需的失效方向，我們將為您配對相應的氣缸。.

這個閥門該如何連接至我的管子？

這是一個薄片式閥體：它位於兩個套圈之間，而夾具則將整個組件固定在一起。閥體本身沒有螺紋或焊接端。.

我可以同時訂購閥門和執行器嗎？

是的，這也是大多數客戶的購買方式。氣瓶是我們的，閥門也是我們的，而且這兩者在出貨前已經完成組裝與配對。.

貴公司是否有最低訂購量？

不。請告訴我們您需要的尺寸和數量，我們會為您報價。.
