2ピース式高圧ボールバルブ、2000 WOG – フルポート、PT／NPTねじ式

製品説明

The V-2NF is a two-piece high pressure ball valve rated 2000 WOG (2000 psi) — twice the rating of a standard 1000 WOG two-piece valve. The body, cap and ball are cast in ASTM A351 CF8M, the cast form of 316 stainless steel, with a full-port bore that matches the pipe inside diameter so flow is not restricted. A CF8 (cast 304) version is made to order.

Female PT and NPT threads are both in stock, sizes 1/4″ to 2″, and every size carries a drilled mounting pad on the body — so a pneumatic or electric actuator can be fitted directly later without changing the valve. It covers hydraulic circuits and high-pressure water, oil and gas lines where a standard-rated valve would be running at its limit.

主要技術仕様

材料

Fourteen parts, matching the numbered circles ①–⑭ in the drawing below. Materials shown for the 316 version in stock; the made-to-order 304 version uses CF8 castings.

Dimensions (mm) & Cv

Cv is the flow coefficient — how many US gallons per minute pass through the open valve at a 1 psi pressure drop. Full drawing in the V-2NF dimension sheet (PDF).

利点とメリット

• Double the pressure rating: 2000 WOG covers hydraulic circuits and pressure spikes that push a standard 1000 WOG valve to its limit.
• Full port, published Cv: the bore matches the pipe inside diameter, and the flow coefficient for each size is in the table above — no guessing at pressure drop.
• アクチュエータ対応： the drilled mounting pad lets you bolt on a pneumatic or electric actuator later — see our air actuated ball valve for the automated option.
• 316 corrosion resistance: CF8M body with added molybdenum resists pitting from chloride-bearing media.

適用分野と設置場所

• Hydraulic systems: shut-off duty on hydraulic circuits running at pressures a standard valve cannot hold.
• High-pressure water, oil & gas lines: chemical, oil & gas piping with elevated working pressure.
• 水処理: pump discharge and distribution points where pressure spikes occur.
• Industrial equipment: machine builders who need a compact threaded valve with a 2000 psi margin.

よくある質問

What does 2000 WOG mean? WOG stands for Water, Oil, Gas — the media the rating covers. 2000 WOG means the valve is rated for 2000 psi working pressure at room temperature, twice the 1000 WOG rating of a standard two-piece ball valve.

When do I need 2000 WOG instead of 1000 WOG? When the line pressure or its spikes approach 1000 psi — hydraulic circuits are the typical case. For general plumbing and process lines, our standard two-piece ball valve at 1000 WOG is usually enough.

フルポートですか？ Yes. The bore matches the pipe inside diameter — see the Bore Ød column in the dimensions table — so the open valve adds almost no flow restriction.

どのようなねじ規格がありますか？ Female PT and NPT are both in stock, sizes 1/4″–2″. Tell us which standard your piping uses when you request a quote.

ステンレス鋼は304と316のどちらを選べばいいでしょうか？ The stock version is cast 316 (CF8M), whose molybdenum resists pitting from chlorides — the safer default for outdoor, coastal and chemical service. A cast 304 (CF8) version is made to order for milder media.
