One Piece Stainless Steel Ball Valve – Reduced Port, 316, 1000 WOG, PT/NPT/PF, 1/4″–3″ (R-1B)

製品説明

A one piece stainless steel ball valve 評価 1000 WOG, with the body cast as a single piece and welded closed. 316 (CF8M) is the stock material; 304 (CF8) is made to order. PTFE seats, manual quarter-turn lever, reduced port, −20 °C to +180 °C. Two end builds: 雌 × 雌 (F×F) 1/4インチから3インチまで、および 男性 × 女性 (M×F) 1/4インチ、3/8インチ、1/2インチ。.

Because the body is one piece instead of two or three bolted or screwed sections, there is no body joint — one fewer place for the valve to leak. The trade-off is honest: it cannot be opened for service, and the bore is one pipe size smaller than the line. We say so plainly further down, and we point you at the valve you should buy instead.

「1000 WOG」が実際に意味すること

WOG の略語 水、石油、ガス. 1000 WOGという定格は、このバルブが以下の条件に対応していることを意味します。 1000 psiの低温、非衝撃使用圧力 on those media.

Three things buyers get wrong about it:

• WOGは耐寒性の指標です。. It is not a steam rating. This valve runs from −20 °C to +180 °C, set by the PTFE seats — tell us your line temperature and we will confirm it suits.
• “「ノンショック」は格付けの一部です。. ウォーターハンマーが発生したり、ポンプの起動が急激に行われたりする配管では、通常の作動圧をはるかに上回る圧力スパイクが生じます。設計の際は、圧力計の表示値ではなく、このスパイクの大きさを基準にしてください。.
• On this valve, “gas” means compressed air. Fuel gas lines (natural gas, propane) call for a gas-listed valve, and this is not one.

冷間時の配管圧力が1000 psiを超える場合は、このバルブは適していません。圧力をお知らせいただければ、適切な製品をお見積もりいたします。.

F×F それとも M×F — どちらが必要ですか？

• 雌 × 雌 (F×F) — 両端ともオス管またはオス継手に対応しています。汎用性の高い選択肢であり、1/2インチ以上（最大3インチ）のサイズで入手可能な唯一の製品です。.
• 男性 × 女性 (M×F) — one male end screws straight into a female port, so you save a fitting and shorten the assembly. Available in 1/4″, 3/8″ and 1/2″ only. If you need M×F above 1/2″, see the two-piece MxF ball valve (1/2″–2″, full port).

Dimensions for both builds are on the PDF dimension sheets at the top of this page.

アプリケーション

A reduced-port, non-serviceable body is a deliberate trade: the smallest envelope and the fewest joints of the three ball valve body types, at the lowest cost of the three. It belongs where those three things matter more than full flow or in-line repair.

• Instrument and gauge line isolation — the shut-off ahead of a pressure gauge or transmitter, so the instrument can be changed without draining the line. Open it slowly; this is an isolation valve, not a throttling one.
• OEM machinery and skid-mounted systems — small-bore utility shut-offs built into a machine frame or a packaged skid, where the valve is replaced as a unit rather than rebuilt in place.
• 狭い場所での設置 — panels, cabinets and pipe runs where a two-piece or three-piece body will not fit. With no mid-body joint there is nothing to add length to the body.
• Compressed air branch isolation — take-offs from a plant air header to a machine, a filter-regulator or a blow-down point.
• Water and oil utility lines — general shut-off on cooling water, wash-down, lubrication and fuel-oil transfer lines up to 1000 psi cold.

Not for pump suction lines (use a full-port valve), fuel gas, steam, potable water or oxygen service — see the table above.

よくある質問

What is a one piece stainless steel ball valve?

A ball valve whose body is cast as a single piece and welded closed, instead of being bolted or screwed together from two or three sections. There is no body joint, so there is one fewer place for a line to weep. The trade-off is that the valve cannot be opened for service and the port is reduced — the bore is one pipe size smaller than the line. If you want the same no-body-joint construction with a full-port bore, see the seal-welded two-piece ball valve (V-2B / V-2C).

「1000 WOG」とはどういう意味ですか？

WOG stands for Water, Oil, Gas. A 1000 WOG rating means the valve is rated for 1000 psi of cold, non-shock working pressure on those media. It is not a steam rating. On this valve “gas” means compressed air — it is not listed for fuel gas.

動作温度範囲はどのくらいですか？

−20 °C to +180 °C, set by the PTFE seats. Tell us your line temperature and we will confirm the valve suits it.

どのようなサイズがありますか？

Female × female (F×F) from 1/4″ to 3″ — 1/4″ to 2″ as standard, 2-1/2″ and 3″ on request. Male × female (M×F) in 1/4″, 3/8″ and 1/2″. Dimensions are on the two PDF dimension sheets at the top of this page.

どのようなねじ規格の製品を取り扱っていますか？

PT（テーパー）が標準のねじ規格です。NPTおよびPFも在庫があります。.

316 or 304 — which should I order?

316 (CF8M) is the stock material and the one to choose wherever chlorides are present: brine, seawater, coastal air, most chemical service. The molybdenum in 316 is what resists chloride pitting. 304 (CF8) is made to order for general water, air and oil duty.

このバルブは、清掃や修理のために開けることはできますか？

No. The body is welded, so it cannot be taken apart. That is the trade-off for having no threaded body joint to leak. If you need to service the valve in line, buy the スリーピースボールバルブ instead. If you only need full-port flow and still want no threaded body joint, the seal-welded two-piece ball valve (V-2B / V-2C) is the one to look at.

これはフルポートバルブですか？

No. It is a reduced (standard) port valve — the bore is smaller than the pipe. If you need full bore flow, buy the seal-welded two-piece ball valve.

そこにアクチュエータを取り付けることはできますか？

No. This body has no actuator mounting pad. If you need automation, buy the one-piece pneumatic ball valve, which has the ISO 5211 pad cast into the body.

材料証明書を発行していただけますか？

はい。ご要望に応じて、製粉証明書を発行いたします。.
