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

Descripción del producto

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 frente a L-Port: ¿cuál necesitas?

Puerto L (Desviador): Dirige el flujo desde la toma inferior hacia la toma izquierda o la derecha (o a la posición «OFF»). Ideal para alternar entre dos depósitos, dos bombas o dos conductos de suministro: una sola válvula se encarga de la conmutación.

Puerto T (Mezclador/Divertidor): 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.

Ambos tipos de racores están disponibles en stock. Para obtener una guía detallada con diagramas de flujo para cada posición de la maneta, consulta nuestro Guía comparativa entre el puerto L y el puerto T.

Especificaciones técnicas clave

Ventajas y beneficios

• Simplificación del sistema: sustituye a varias válvulas de dos vías y racores en T, lo que reduce los costes de instalación y el espacio necesario.
• Gestión versátil del caudal: mezclar, desviar o aislar el caudal en función de la configuración de los puertos elegida.
• Compatible con actuadores: Gracias a la placa superior de tipo ISO, podrás automatizar esa misma válvula más adelante sin necesidad de volver a instalar las tuberías.
• Resistencia a la corrosión: El acero inoxidable 316 con molibdeno añadido resiste la corrosión por picaduras provocada por medios que contienen cloruro, tanto en interiores como en exteriores.

Aplicaciones

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.

Preguntas frecuentes

Puerto en L o puerto en T: ¿cuál debería elegir? 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.

¿Puede una válvula de bola de tres vías cortar el flujo por completo? 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.

¿Se puede automatizar esta válvula más adelante? 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 válvula de bola neumática de tres vías.

¿Qué normas de rosca hay disponibles? 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.

¿Cuál es el rango de temperatura de funcionamiento? −20 °C to +180 °C (−4 °F to +356 °F), limited by the PTFE seats. The valve is not rated for steam service.

304 o 316: ¿cuál debería elegir? La válvula estándar es la CF8M (acero inoxidable 316 fundido), disponible en stock; su contenido en molibdeno la hace resistente a la corrosión por picaduras provocada por los cloruros. La CF8 (acero inoxidable 304 fundido) se fabrica bajo pedido para aplicaciones generales con agua y aire.
