Ball Valve with Actuator — Pneumatic 3-Piece 316, ISO 5211 Direct Mount, 1000 WOG (V-3AM)

Descripción del producto

This is a ball valve with actuator — a 3-piece stainless steel valve with a pneumatic actuator mounted directly on it — built to solve the headache of servicing welded or threaded automated lines. By removing the body bolts, the central valve section (with the actuator still attached) can be removed or swung out for inspection. That matters most where seals wear out from high cycle rates, or where a line has to be opened and put back the same shift.

The valve is a 3-piece full port stainless steel ball valve with an ISO 5211 mounting pad, driven by a rack-and-pinion aluminum alloy pneumatic actuator in Double Acting (DA) or Spring Return (SR) versions. The ISO 5211 pad is part of the valve body, so the actuator bolts straight down onto it — there is no separate bracket and coupling kit to source and align. 316 stainless steel is in stock; 304 is made to order. For how pneumatic automation fits stainless valve lines, see our pneumatic valve automation guide.

Why a 3-Piece Body Is Right for a Ball Valve with Actuator

• Lowest maintenance cost: seals can be replaced without demounting the actuator or cutting the assembly out of the pipe.
• High-cycle durability: automated lines open and close far more often than manual ones — the serviceable body keeps that from becoming a replacement cost.
• Weld-in without cooking the actuator: with weld ends, the body can be welded into the line first and the actuator mounted after, protecting pneumatic components from heat.
• Válvula a prueba de reventones and live-loaded PTFE seats on the valve section.

Campos de aplicación

• Chemical and petrochemical processing: transfer, dosing and reactor feed lines carrying acids, alkalis and solvents — lines that have to be opened and closed from a control room rather than by hand.
• Chemical injection on oil and gas surface facilities: corrosion inhibitor, biocide and demulsifier injection points, often at unmanned sites. A spring return actuator drives the valve to its safe position when the air supply is lost.
• Water and wastewater treatment: coagulant, polymer and caustic soda dosing manifolds, where the dose rate follows water quality and the seats need cleaning on a schedule.
• Pulp and paper: isolation on chlorine dioxide bleaching and caustic lines, where a fast quarter-turn shut-off is part of the safety case.
• Plant utilities: low-pressure steam, condensate, cooling water, compressed air and nitrogen isolation, within the -20 °C to +180 °C body rating.
• Tank farms and loading stations: solvent, acid and alkali storage lines, interlocked with level switches so the valve closes on high level.

Preguntas frecuentes

Does the ball valve come with the actuator already fitted? Yes. The actuator is mounted on the valve at our factory and the two ship together as one unit, so there is no bracket or coupling to source and align on your side. Tell us DA or SR and the end connection you need when you request a quote.

Doble acción (DA) o retorno por resorte (SR): ¿cuál debería elegir? Un actuador DA utiliza presión de aire tanto para abrir como para cerrar la válvula. Un actuador SR utiliza un resorte para llevar la válvula a una posición de seguridad preestablecida (abierta o cerrada) en caso de que se interrumpa el suministro de aire. Elige el modelo SR cuando sea necesario que la línea cuente con un sistema de seguridad; elige el modelo DA para aplicaciones generales de encendido/apagado.

¿Puedo cambiar los asientos sin tener que cortar la válvula de la tubería? Sí. Al retirar los tornillos del cuerpo, la sección central se abre hacia fuera sin necesidad de desmontar el actuador; así, se puede realizar el mantenimiento de los asientos y las juntas sin desmontar nada, y a continuación se vuelve a montar el cuerpo.

¿Qué suministro de aire necesita el actuador? 4 to 8 bar (about 58 to 116 psi) of clean, dry compressed air.

¿Qué significa la norma ISO 5211? ISO 5211 is the standard for actuator mounting pads. The valve carries an F03–F10 pad depending on size (the size-to-pad chart is in the dimension PDFs at the top of this page), so the actuator mounts directly — no bracket — and can be swapped for another ISO 5211 actuator later.

¿Qué conexiones finales hay disponibles? Threaded ends in PT, NPT and PF — all in stock — plus socket weld and butt weld. For the JIS-standard butt weld automated valve, see our actuated butt weld ball valve página.

¿Cuál es la temperatura nominal? The valve body is rated -20 °C to +180 °C (-4 °F to +356 °F), limited by the PTFE seats. The actuator is rated -20 °C to +80 °C, so the combination is limited by whichever part is reached first — tell us your service temperature when you request a quote and we will confirm it.
