Yes — every size. The bore matches the pipe inside diameter (see the Bore column in the dimensions table), so the open valve adds almost no flow restriction.

Product Description

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. Prefer a hand lever? See the manual two-piece ball valve, or browse all pneumatic ball valves.

Double-Acting or Spring-Return?

	Double-acting (DA)	Spring-return (SR)
How it moves	Air pressure drives the valve both open and closed	Air drives one way; springs drive the return stroke
If air is lost	Valve stays where it was	Springs move the valve to its preset open or closed position
Best for	General automated on/off duty	Lines that must land in a defined position when air supply drops

Application Fields & Locations

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.
Water treatment: valve sequencing across filtration and distribution stages.
Chemical & process lines: remote shut-off where 316 corrosion resistance matters.

FAQ

Double-acting or spring-return — which should I choose? 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.

Can I add a solenoid valve or limit switch? 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.

Is it full port? 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.

What is the minimum order? No minimum order quantity — we accept orders of any size, including small trial orders. For small orders, freight is arranged and paid by the buyer. Payment is by T/T — 30% on order confirmation, 70% before shipment.
