Robinet à boisseau sphérique manuel à 3 voies – Acier inoxydable 316, raccord en L/T, 1 000 WOG

Description du produit

This manual 3 way ball valve in 316 stainless steel eliminates complex piping manifolds: divert flow or mix fluids with a single 3T/3L Series valve instead of multiple 2-way valves and tee fittings. PT threaded, rated 1000 WOG, with PTFE seats — and an ISO-style mounting pad, so the same valve can take a pneumatic or electric actuator later.

T-Port vs L-Port — Which One Do You Need?

L-Port (Diverter) : directs flow from the bottom port to either the left or right port (or OFF). Ideal for switching between two tanks, two pumps or two supply lines — one valve does the changeover.

Port en T (mélangeur/diffuseur) : 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.

Both port types are in stock. For a full walkthrough with flow-path diagrams for every handle position, see our L-port vs T-port guide.

Caractéristiques techniques principales

Avantages et bénéfices

• System simplification: replaces multiple 2-way valves and T-fittings, reducing installation cost and space.
• Versatile flow management: mixing, diverting or isolating flow depending on the port configuration chosen.
• Actuator-ready: the ISO-style top pad means you can automate the same valve later — no re-piping.
• Corrosion resistance: 316 stainless steel with added molybdenum resists pitting from chloride-bearing media, indoors or outdoors.

Dimensions (mm) — MV-3M

Key dimensions in millimetres. Full stem and mounting-pad details are in the MV-3M dimension sheet (PDF).

Domaines d'application et emplacements

• Systèmes CVC: by-pass lines and temperature mixing loops.
• Traitement chimique: switching between ingredient lines or reactors.
• Tank farms: routing product between storage tanks with one valve.
• Water systems: alternating supply lines and filtration loops.

FAQ

L-port or T-port — which should I choose? 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.

Can a 3-way ball valve shut off flow completely? The L-port ball can be rotated to an OFF position between outlets. The T-port is designed for mixing and diverting — tell us your switching pattern and we will confirm the right ball and stopper configuration.

Can this valve be automated later? 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 pneumatic 3-way ball valve.

Which thread standards are available? PT (tapered) threads are in stock. NPT and PF can be made to order — tell us which standard your piping uses when you request a quote.

What is the working temperature range? -20 °C to +180 °C (-4 °F to +356 °F), limited by the PTFE seats.

304 ou 316 — lequel choisir ? The standard valve is CF8M (cast 316), in stock — its molybdenum content resists pitting from chlorides. CF8 (cast 304) is made to order for general water and air duty.
