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

產品說明

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-Port 對比 L-Port —— 您需要哪一種？

L 端口（轉向器）： 將流量從底部接口導向左側或右側接口（或關閉）。非常適合在兩個儲槽、兩台泵浦或兩條供料管線之間切換——僅需一個閥門即可完成切換。.

T 端口（混合器/轉換器）： 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.

這兩種接頭型號均有現貨。如需包含每個手柄位置之流路圖的完整操作指南，請參閱我們的 L 型連接埠與 T 型連接埠對比指南.

主要技術規格

優勢與好處

• 系統簡化： 可取代多個雙向閥和 T 型接頭，從而降低安裝成本並節省空間。.
• 多功能流量管理： 根據所選的接口配置，可進行混合、分流或隔離流體。.
• 支援致動器： 採用 ISO 規格的頂部接頭，意味著您日後可將同一閥門自動化——無需重新佈管。.
• 耐腐蝕性： 添加鉬的 316 不鏽鋼，無論在室內或室外環境中，皆能抵抗含氯化物介質所造成的點蝕。.

應用

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.

常見問題

L 型接頭還是 T 型接頭——我該選哪一個？ 若需在兩個目的地（兩個儲槽、兩台泵浦、兩條管路）之間切換流量，請選擇 L 型接頭——它可將流向轉向 90°，並具備關閉功能。若需將兩條管路合併為一條、讓流體直通，或導向第三個接頭，請選擇 T 型接頭。這兩種接頭均有現貨。.

三通球閥能否完全切斷流量？ 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.

這個閥門日後能否實現自動化？ 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 氣動三通球閥.

有哪些螺紋標準可供選擇？ 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.

工作溫度範圍為何？ −20 °C to +180 °C (−4 °F to +356 °F), limited by the PTFE seats. The valve is not rated for steam service.

304 還是 316 —— 我該選哪一種？ 標準閥門為 CF8M（316 鑄件），現貨供應——其鉬含量可抵抗氯化物引起的點蝕。CF8（304 鑄件）則為一般水與空氣用途而接受訂製。.
