提升塞式儀表閥
提升塞式儀表閥採用軟密封直通提升塞內件而非針形閥桿，髒污或黏性介質可用通條疏通且閥座抗堵——這是高振動與壓力/溫度循環的油氣、化工與電力嚴苛服務中的儀表隔離閥。產品範圍涵蓋工作壓力至 6000 psig（413 bar）、-53°C 至 315°C 服務、Cv 至 1.65、孔徑 0.187 與 0.250、閥體與閥帽 316 不鏽鋼或 Alloy 400、Acetal/PFA/PEEK 閥座與活載 PTFE 或 PEEK 填料。選型取決於通條疏通需求、閥座材料對介質，以及振動場所的鎖定閥帽硬體。參考資料補充儀表閥任務框架（隔離、排放積壓、拆卸或校準儀表）、以 acetal/PFA/PEEK 可更換閥座為限額的額定邏輯、棒料閥體上的不可旋轉閥桿尖端、氣泡級高壓結構包絡、通條疏通直孔，以及涵蓋隔離與計量任務的 V 型桿/調節/軟密封閥桿尖端選項。

系列規格
| Flow Coefficient | up to 1.65 |
|---|---|
| Temperature (source-defined) | -53°C to 315°C (-65 to 600° F) |
| Pressure (source-defined) | up to 6000 psig (413 bar) |
| valve orifice sizes | 0.187, 0.250 |
| Body-and-bonnet material specification | 316 stainless steel, Alloy 400 |
| Seat material | Acetal, PFA, PEEK |
| packing material | PTFE, PEEK (with PEEK seat only) |
| gauge valve function | Isolates a pressure gauge, switch or transmitter from the process; trapped pressure can be vented so the instrument is removed, tested or calibrated safely |
| size and connection example | Rising-plug soft-seat executions commonly run 1/2 or 3/4 in. male NPT process inlet with female NPT instrument outlet and gauge ports |
| seat temperature limits | Seat-limited execution envelope: acetal to 250°F; PEEK to 450°F or higher on some designs |
| replaceable soft seat | Replaceable soft seat available in acetal, PFA or PEEK |
| seat limited rating rule | Soft seats limit the valve rating well below the body limit; exact ratings are confirmed against selected size, material, seat, packing and end connections |
| non rotating stem tip | Bar-stock bodies with a non-rotating stem tip keep the seat from being twisted as the valve closes |
| bubble tight envelope | Bubble-tight sealing at 6000-10,000 psi and -40°C to 230°C on high-pressure executions |
| regenerative soft seat | Rising plug valve delivers bubble-tight isolation with a regenerative soft seat |
| clear bore roddable | Clear-bore design allows high flow and precise control and is roddable for easy maintenance |
| stem tip options | Stem-tip choices span v-stem, regulating and soft seat, covering hydraulic and pneumatic applications |
| metering duty | Instrument valves also suit flow-metering duty, maintaining a calibrated and constant low flow rate |
| product family placement | Rising plug valves are offered as the RP series within instrument needle-valve ranges |
| rga steam water temp limit acetal | not recommended for temperatures greater than 200F (93C) |
| rga high temp seat extension | 400F (204C) with PEEK or PFA seat material |
| rga nitrogen factory test | factory tested with nitrogen at 1000 psig (69 bar) |
| rga seat leak limit | maximum allowable leak rate of 0.1 std cm3/min |
| rga api624 methane limit | leak in excess of 100 ppm of methane |
| rga sour gas materials standard | in accordance with NACE MR0175/ISO 15156 |
| rga body materials | 316 SS/ A276, A479 Alloy 400/ B164 |
| rga seat material options | Acetal/D6778, PEEK, or PFA/D3307 |
| rga panel mount limits | panel thickness is 1/2 in. (12.7mm), and the panel hole size is 25/32 in. (19.8mm) |
| rga cv orifice series | 0.63 0.187 (4.8), 1.80 0.250 (6.4) |
| rgb sour gas availability | Sour gas service available |
| rgb factory testing | 100% factory tested |
| rgb seat material options | POM Cone Seat is standard for easier replacement and PEEK is also available as option |
| rgb temp rating pom | -20F ~ 250F (-29C ~ 121C) |
| rgb temp rating peek | -20F ~ 400F (-29C ~ 204C) |
| rgb max temp pressure | 1,000 psig (69bar) @ 400 F (204 C) |
| rgb internal seal | prevent ingress of foreign materials into the actuating threads |
| rgb end connections | include male/female NPT and Male/Female ISO/BSP |
| rgc multiport gauge valves | multiport gauge valves are equipped with vent and blanked port facilities |
範圍與來源備註
| pressure envelope split | Pressure envelope split: referenced bubble-tight executions reach 10,000 psi while the tenant page tops at 6000 psig - the upper band belongs to selected seat/body combinations outside the tenant range. |
|---|---|
| temperature envelope | Temperature envelope: referenced -40°C to 230°C bubble-tight execution vs tenant -53°C to 315°C - both are seat-material dependent and the tenant extremes rely on PEEK/graphite builds not evidenced in the referenced execution. |
| seat limit rule | Seat limit rule: acetal 250°F / PEEK 450°F referenced ceilings sit inside the tenant 315°C service claim - the tenant upper band depends on the PEEK build plus packing, not the soft seat alone. |
| duty framing | Duty framing: clear-bore high-flow rodding duty vs calibrated low-flow metering framing - the rising-plug execution spans both, but a single stem-tip choice (v-stem vs regulating vs soft seat) cannot serve both extremes. |
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。
