Vanne à bille pneumatique en deux parties en acier inoxydable 316

Description du produit

This 2-piece pneumatic ball valve pairs our V-2AM direct-mount valve with a rack-and-pinion air actuator — double-acting (DA) or spring-return (SR). The valve body, cap and ball are cast 316 stainless steel (ASTM A351 CF8M), full port on every size, rated 1000 WOG, with PTFE seats. A quarter-turn of the actuator opens or closes the line in under a second.

The ISO 5211 mounting pad is cast into the valve, so the actuator bolts straight on — no bracket, no coupling to fabricate. Female PT threads are in stock, sizes 3/8″ to 4″ (DN10 – DN100); NPT and PF can be made to order. Need more end options like socket weld or butt weld? See the 3-piece air actuated ball valve.

Domaines d'application et emplacements

• Automated on/off duty: water, air and light chemical lines controlled by PLC or remote signal.
• Machine builders: a compact valve-plus-actuator unit that bolts together without brackets, in ten sizes.
• Traitement de l'eau: valve sequencing across filtration and distribution stages.
• Chemical & process lines: remote shut-off where 316 corrosion resistance matters.

FAQ

Double effet ou retour par ressort : lequel choisir ? Double-acting (DA) uses air for both strokes and stays in its last position if air is lost. Spring-return (SR) uses springs for the return stroke, so on air loss the springs move the valve to its preset open or closed position — specify which when you order.

Puis-je ajouter une électrovanne ou un interrupteur de fin de course ? Yes. The actuator accepts a solenoid valve for electrical control, a limit switch box for position feedback, and a positioner for modulating service — tell us your control setup when you request a quote.

2-piece or 3-piece pneumatic — which should I choose? The 2-piece is the compact, economical choice for threaded lines. Choose the 3-piece air actuated ball valve when you need socket-weld or butt-weld ends, or want to service the seats without cutting the valve out of the line.

Est-ce un port complet ? Yes — every size. The bore matches the pipe inside diameter (see the Bore ØD column in the dimensions table), so the open valve adds almost no flow restriction.

Which thread standards are available? Female PT threads are in stock, sizes 3/8″–4″. NPT and PF can be made to order — tell us which standard your piping uses when you request a quote.
