| diverting ports | 3-Way multi-port diverting and mixing |
| sealant functions | Drop-Tight Seal, Lubrication, Renewable Seat, Plug-Jacking |
| lubricant temperature grading example | 50-650 F (10-343 C) stick-grade sealant example |
| sleeved seat envelope | PTFE sleeved approx. -20 to 200 C, up to 40 bar (600 psi) |
| eccentric seat action | 20-30 degree offset between plug and seat; cam-action lift before rotation minimizes seat rubbing |
| fire testing standards | API 607, API 6FA |
| ptfe sleeve temp ceiling | Standard PTFE sleeve limits service to about 200°C max; sleeved plug valves are unsuitable for high-temperature steam or heavy hydrocarbon service where PTFE would degrade |
| ptfe sleeve sealing mechanism | Bubble-tight zero-leakage sealing; self-lubricating sleeve reduces wear and friction; smooth non-stick lining prevents buildup of scale, debris, or chemical residues |
| lubricated in line resealing | Lubricated plug valves can be resealed and recovered in service without removal from the line |
| eccentric leakage and direction | Eccentric plug valves seal in both flow directions; soft-seated eccentric valves often achieve ISO 5208 Class VI leakage |
| eccentric slurry wear mechanism | Cam-away opening action prevents abrasive media from cutting grooves in the seat as the plug rotates; eccentric plugs are used in severe sewage service (DN100–DN600) |
| low emission certification | Low-emission sleeved plug valves certified to ISO 15848-1 / TA-Luft 2021 exist (e.g. XOMOX sleeved plug valves passed four thermal cycles without packing adjustment, BH CO3 200°C SSA0) |
| sour service materials standard | NACE MR0175 / ISO 15156 for sour (H2S-containing) oil & gas service; MR0103 governs refinery (downstream) sour service |
| sour service hardness limit | Carbon and low-alloy steel pressure-containing parts (body, bonnet, end flanges) max 22 HRC (237 HBW, 248 HV10) for NACE MR0175 compliance |
| sour service h2s threshold | H2S partial pressure exceeding 0.0003 MPa (0.05 psi) in a multiphase system with free water present defines sour service |
| sour service fire safe | Fire-safe design to API 607 required for plug valves (with ball and butterfly valves) in sour flammable service |
| sour service trim note | Standard bearing balls and 440C trim are not permitted in sour valves; cobalt-chromium hardfacing alloy 6 hardfacing is permitted |
| eccentric size range large diameter | 0.5 - 72 in (15 - 1800 mm) (DeZURIK PEC/PEF eccentric plug valves) |
| eccentric temperature ceiling | 450 F (232 C) (DeZURIK PEC/PEF) |
| eccentric shutoff class | Resilient plug facing: drip tight; metal plug: equal to ANSI/FCI 70-2 Class IV (DeZURIK PEC/PEF) |
| eccentric port area options | 100% of standard pipe area where highest flow is required (pumped systems); 70/80% area for non-pumped (gravity feed) systems; straight-through body maximizes flow capacity and reduces head loss (DeZURIK PEC/PEF) |
| eccentric pressure rating pec pef | PEC: cast iron 0.5-12 in 175 psi (15-300mm 1210 kPa), 14-72 in 150 psi (350-1800mm 1035 kPa); ductile iron 0.5-12 in 285 psi (1965 kPa), 14-72 in 250 psi (1724 kPa); special 450 psi (3100 kPa). PEF: cast iron or ductile iron 3-12 in 175 psi, 14-36 in 150 psi. |
| eccentric rectangular port seating | Quarter-turn eccentric action with resilient plug facings; the plug moves eccentrically into a raised eccentric seat without scraping the seat or body walls, and the rectangular port provides wide tolerance seating geometry for lasting shutoff (DeZURIK PEC/PEF) |
範圍與來源備註
| eccentric size range inconsistency | Eccentric size-range inconsistency: generic sources cap plug valves at DN15-DN600 (1/2"-24") while DeZURIK publishes the PEC/PEF eccentric execution to 72 in (DN1800); kept generic field unchanged, execution-specific range recorded separately. |

訂購與文件
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。
常見問題
旋塞閥的報價詢問應包含哪些內容？

油潤滑旋塞閥
油潤滑旋塞閥在塞與閥體之間維持蠟狀密封：注入的油脂複合物沿密封面分布，降低操作扭矩，並使錐形塞在含砂或黏性管介質中擦拭自淨。產品範圍涵蓋油潤滑型結構 DN15 至 DN400（1/2 至 16 吋），額定 PN10 至 PN420 與 Class 150 至 2500，端接為 RF、NPT、對焊或承插焊，操作為手動、氣

套筒旋塞閥
套筒旋塞閥將錐形塞置於壓縮套筒——通常為 PTFE 基材——內，套筒與塞面磨合並維持管線密封而無需注入密封脂，這使其在乾燥、衛生或對污染敏感的服務中贏得非潤滑型的定位。產品範圍涵蓋 DN15 至 DN350 結構，額定 Class 150 至 900 與 PN16 至 PN63，閥體與閥蓋為 WCB、CF8、CF8M、

夾套旋塞閥
夾套旋塞閥在閥體外帶加熱夾套，使管線蒸汽或熱媒能將含蠟、易凝或熱敏感介質保持在流動點以上，同時旋塞進行節流或截斷——這是瀝青、硫磺、巧克力與重油迴路上會在普通鑄件中凝固的介質的標準答案。產品範圍涵蓋 1/2 至 24 吋（DN15 至 DN600）結構，額定 Class 150 至 2500 與 PN16 至 PN42

三通旋塞閥
三通旋塞閥經單一塞體連通兩個入口與一個出口（或反之），分流或匯流的切換在閥門處完成，而非在由兩顆二通截斷閥組成的三通接頭中——適用於混合任務、輸送線選擇與取樣或沖洗取口。產品範圍涵蓋 DN15 至 DN300 結構，額定 Class 150 至 2500 與 PN10 至 PN420，依 API 599 與 API 6

偏心旋塞閥
偏心旋塞閥將圓弧形塞擺入偏置閥座，僅在關閉位置以凸輪方式壓緊閥座面——每次行程閥座是被擦拭而非刮擦，因此在含砂、含纖維或結垢的水與污水服務中保持密封，而直動式旋塞會磨損閥座。產品範圍涵蓋鑄鐵 RF 法蘭結構，NBR 或 EPDM 閥座，尺寸 DN15 至 DN400（1/2 至 16 吋），額定 PN10 至 PN16

軌道式旋塞閥
軌道式旋塞閥在旋轉之前先將塞從閥座提起，密封面僅在行程最後一小段發生摩擦——滾動與彎曲複合運動使其在循環服務、顆粒介質與漿料中保持嚴密關斷，而傳統 1/4 迴轉閥會將砂粒碾過閥座。產品範圍涵蓋 DN15 至 DN350 結構，額定 Class 150 至 2500 與 PN16 至 PN420，依 API 599、AP
