Stainless Steel 3-Way Ball Valve – Manual, L-Port or T-Port, 316 CF8M, 1000 WOG, PT 1/4″–2″ (MV-3M)

製品説明

This stainless steel 3-way ball valve replaces two shut-off valves and a tee fitting with one body: divert flow between two lines with an L-port ball, or mix two streams into one with a T-port ball. Both ball types are stock builds — 3L and 3T of the same MV-3M series — in ASTM A351 CF8M, the cast form of 316 stainless steel; CF8 (cast 304) is made to order.

Sizes run 1/4″, 3/8″, 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″ and 2″ with female PT threads in stock; NPT and PF are made to order. Rated 1000 WOG with PTFE seats, −20 °C to +180 °C, for water, oil and compressed air. An ISO-style mounting pad is cast into the top, so the same valve can take a pneumatic or electric actuator later without re-piping.

Tポート対Lポート — どちらが必要ですか？

Lポート（ダイバータ）： 下部のポートからの流れを、左または右のポート（あるいは「OFF」）のいずれかに導きます。2つのタンク、2つのポンプ、あるいは2つの供給ラインを切り替えるのに最適です。1つのバルブで切り替えが可能です。.

Tポート（ミキサー／分岐器）： can connect all three ports simultaneously (mixing two lines into one), or direct flow straight through or at 90 degrees. Ideal for blending duty and bypass loops around strainers, meters or heat exchangers. Note that a T-port ball keeps at least two ports open in every handle position — it is a switching and mixing valve, not a shut-off valve; use the L-port build when you need an OFF position.

どちらのポートタイプも在庫がございます。各ハンドル位置ごとの流路図を含む詳細な手順については、当社の LポートとTポートの比較ガイド.

主要技術仕様

利点とメリット

• システムの簡素化： 複数の2方向弁やT字継手を置き換えることで、設置コストと設置スペースを削減します。.
• 多彩な流量管理： 選択したポート構成に応じて、流体の混合、分流、または隔離を行います。.
• アクチュエータ対応： ISO規格のトップパッドを採用しているため、後で同じバルブを自動化することも可能です。配管のやり直しは必要ありません。.
• 耐食性： モリブデンを添加した316ステンレス鋼は、屋内・屋外を問わず、塩化物を含む媒体による孔食に耐性があります。.

アプリケーション

A 3-way ball valve earns its place wherever an operator has to send flow one way or the other, or blend two streams. Typical duties:

• Tank-to-tank source switching (L-port): selecting which of two storage tanks feeds a line, or routing product from one tank to another, with a single valve instead of two shut-offs.
• Duty / standby pump switching (L-port): connecting either the duty or the standby pump to the downstream line, so operators can change pumps without re-piping.
• Bypass around a filter or heat exchanger (L-port): routing flow around equipment taken offline for service in general industrial plants, instead of operating several isolation valves.
• Sample and stream selection: switching between process streams to send one to a sampling point or analyser, or purging a sample line before analysis.
• Duplex strainer changeover (T-port): switching between two strainer or filter vessels so the offline side can be serviced without stopping flow.
• Hot and cold water blending (T-port): mixing two supply streams in variable proportion to hit a target outlet temperature in building HVAC and process water loops.
• Chemical blending and dispense/recirculation switching (T-port): proportioning two liquid streams, or switching a feed line between a dispense path and a recirculation loop in chemical processing.
• Compressed air routing: directing plant air to one of two downstream lines or tools, or venting one line while supplying another.

Not for potable water, fuel gas (natural gas or LPG), steam, oxygen or cryogenic service — those duties need valves certified or built for them.

よくある質問

LポートとTポート――どちらを選べばいいのでしょうか？ Choose L-port to switch flow between two destinations (two tanks, two pumps, two lines) — it diverts 90° and can also shut off. Choose T-port to mix two lines into one, run straight through, or divert to a third port. Both are in stock.

3方向ボールバルブは、流れを完全に遮断できますか？ The L-port ball can be rotated to an OFF position between outlets. The T-port ball keeps at least two ports connected in every position, so it switches and mixes but does not isolate — tell us your switching pattern and we will confirm the right ball and stopper configuration.

このバルブは、後から自動化することは可能ですか？ Yes. It has an ISO-style top mounting pad, so a pneumatic or electric actuator mounts directly. If you want it supplied automated, see our 空圧式3方ボールバルブ.

どのようなねじ規格がありますか？ Female PT (taper) threads are in stock, sizes 1/4″–2″. NPT and PF are made to order — tell us which standard your piping uses when you request a quote.

動作温度範囲はどのくらいですか？ −20 °C to +180 °C (−4 °F to +356 °F), limited by the PTFE seats. The valve is not rated for steam service.

304と316、どちらを選べばいいでしょうか？ 標準バルブはCF8M（鋳造316）で、在庫があります。この材質はモリブデンを含有しているため、塩化物による孔食に耐性があります。CF8（鋳造304）は、一般的な水や空気の用途向けに受注生産されます。.
