SS316L 固定球閥（API 6D）
SS316L 球閥軸的大口徑錨點：API 6D 全通徑固定球結構，24 吋（DN600）、900LB（PN150），SS316L 球體與閥桿、尼龍閥座、對焊端配 600 mm API 5L X60 接管，氣動-油壓驅動與遠程遙測（型號 LV 14 TBV 06）。固定球安裝正是讓 24 吋球體承載 Class 900 而無需浮動設計的閥座負載與扭矩的原因。
屬於 固定球閥（Trunnion Mounted） 系列

應用與選型指引
Specify this execution class for large-diameter stainless transmission and process headers to API 6D: SS316L for corrosion duty, full bore for pigging, welded ends for buried or fully-welded pipelines, and actuated operation for remote installations. Confirm the seat material (nylon here) against medium temperature - the polymer seat, not the SS316L body, sets the temperature window.
常見問題
Why trunnion mounting at 24 inch and 900LB?
A floating 24-inch Class 900 ball would press the full line load onto the downstream seat and need enormous operating torque; trunnion mounting fixes the ball on bearings so seat load and torque stay manageable - the standard design route for large-diameter high-class ball valves under API 6D.
What are the exact specifications of the benchmark model?
Model LV 14 TBV 06: 24 inch (DN600), 900LB (PN150), full bore, trunnion mounted, SS316L ball and stem, NYLON seat, API 6D, butt-welded ends with 600 mm API 5L X60 pups of 12.7 mm wall, gas-over-oil actuator with remote telemetry.
Is this execution pipeline-service compliant?
API 6D is the pipeline-valve standard covering trunnion design, welded ends and testing; the welded ends with X60 pups are intended for direct field welding into an API 5L pipeline. Verify additional pipeline requirements (double block and bleed, sealant injection) at enquiry.

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。
