應用與選型指引
Select this execution for abrasive, slurry or granular duty where a simple manual isolate valve with a full elastomer flow path outlasts metal-seated alternatives: the sleeve is the only wear part and is replaced in service without cutting the body. Choose the body material against the environment (cast iron for utility duty, stainless for corrosive wash-down), and match the PN10/16 or 150LB flanging standard - ANSI, DIN or JIS - to the mating pipe class.
常見問題
How does a platen-type pinch valve close the line?
The handwheel drives a trolley and platen that press the elastic rubber bushing from the outside until the passage collapses; only the bushing touches the medium, so abrasive or granular solids never reach seats, gates or packing. Releasing the handwheel lets the bushing spring back to full bore.
Which sizes and ratings does this execution cover?
The benchmark page lists nominal sizes DN25 to DN150 at nominal pressures PN10, PN16 and 150LB, with flanged ends to ANSI B16.5, DIN 3202 and JIS - a utility and process envelope suited to slurry, powder and wastewater lines within that span.
What must be replaced on service?
The rubber bushing is the single media-contact wear part - the cast iron body, platen and trolley stay out of the flow. Bushing replacement is an in-line maintenance task on the benchmark construction, which is why the execution is favoured where metal-seated valves would erode quickly.

文件
請在詢問時一併說明您需要的文件組合——此結構的常見項目（材質證明、按所列檢驗標準的測試報告、尺寸圖）將於報價時確認並隨附供應。
報價
可直接報價的詢問應說明：公稱口徑與壓力額定、閥體與閥座材質偏好、端部連接、操作方式，以及含溫度的使用介質。本頁的典型值為基準參考範圍；具有約束力的數值於報價時確認。
樣品與供應
供應條件、訂購數量與交期按訂單議定——請在詢問時說明目的地國家與所需時程。
儲存與運輸
閥門儲存時應保護閥座與密封件免受紫外線、臭氧與變形影響，安裝前保留端面保護蓋；彈性體或 PTFE 閥座結構應避免長期戶外存放——閥座材料在陽光直射與冰凍條件下老化最快。
