Product Name
Air Actuated Ball Valve – One-Piece 3/8″, Integral ISO 5211 Direct Mount Pad, No Bracket (1PC-PN)
Product Summary
Air actuated ball valve, supplied as one assembly. The 1PC-PN one-piece valve body carries an integral ISO 5211 pad, so the rack-and-pinion air actuator bolts straight on — no bracket, no coupling. Double-acting (DA) or spring-return (SR), air supply 4–8 bar, on/off duty. Also available as the valve alone, to fit your own actuator.

Product Description
An air actuated ball valve supplied as one assembly: a one-piece 3/8″ stainless steel valve body with a rack-and-pinion air actuator bolted straight onto it. Body in 316 or 304, both made to order.
There is no bracket and no coupling. The ISO 5211 mounting pad is part of the valve body itself — cast as one piece with it, not bolted on afterwards. That single fact is why this valve outlasts most small automated ball valves, and it is worth two minutes of your time to understand why.
Why No Bracket Matters
Most small pneumatic ball valves on the market are four separate parts stacked on top of each other: the valve, a steel bracket, a coupling, and the actuator. Every one of those joints is a place where things go wrong.
| Valve + bracket + coupling + actuator | This valve |
|---|---|
| The bracket bolts work loose. Every cycle puts torque through them. Nobody checks them until the valve stops turning. | No bracket to loosen. The pad is part of the body. |
| The coupling can sit off-centre. A misaligned coupling wears the stem and the actuator shaft on every stroke. | Nothing to misalign. The actuator seats directly on the integral pad, concentric with the stem. |
| Four parts to source, four to stock, four to blame when it fails | Valve and actuator, assembled and tested by us before it ships |
| Taller assembly — harder to fit in a machine frame | Shorter. The actuator sits down on the body. |

The pad is ISO 5211 standard, so it is not a proprietary fitting — you are not locked into us for the actuator. Prefer to fit your own? The valve is also available on its own, pad included, without the actuator.

On/Off Only — Do Not Buy It to Throttle
This valve opens and it closes. It is not a control valve. We do not offer a positioner for it, and we will not sell you one that is half-open all day.
A ball valve held part-way open puts the full flow across one edge of the ball and one edge of the seat. The PTFE cuts, the seat leaks, and you are back to us in a year. If you need to modulate flow rather than shut it, tell us what you are trying to do and we will say honestly whether we have the right valve for it.
DA or SR — Which Actuator?
- Double acting (DA) — air drives it open, air drives it closed. Lose the air and the ball stays where it was.
- Spring return (SR) — air drives it one way, a spring returns it the other. Lose the air and the spring takes over, so the valve lands in a known position.
Tell us which way the valve must go when the air fails, and we fit the matching cylinder. If you are driving it from a PLC, add our NAMUR solenoid valve — it bolts onto the actuator with no tubing between them, and the whole package ships assembled and tested.
Applications
- Compressed air and utility gas isolation — an on/off shutoff point on compressed air and general utility gas lines, where the pressure drop of a reduced port is not a concern.
- Space-constrained OEM equipment and skid-mounted systems — the integral ISO 5211 pad lets the actuator bolt directly to the body, no bracket or coupling, so the assembly stays short and fits inside a machine frame or a crowded skid.
- PLC-controlled on/off isolation points — remote-actuated shutoff valves in automated systems, such as skid inlet and outlet points, where the valve only has to open or close on command.
- General utility water and water-like process fluids — service water lines and process fluids with water-like flow characteristics, where isolation rather than throttling is the job.
- Automated drain and condensate discharge — the shutoff element in pneumatically actuated drain assemblies, such as compressed-air condensate drains triggered by a float or level signal.
Buying From Us
- Manufacturer, not a trading company. Our own factory in Taiwan, stainless valves since 1999.
- Valve, actuator and solenoid from one supplier — assembled, matched and tested before it ships. Nothing to work out on site.
Tell us the medium, DA or SR, the thread, and whether you want the solenoid fitted. That is enough for us to quote.
FAQ
Does this valve need a mounting bracket?
No. The ISO 5211 mounting pad is part of the valve body — cast as one piece with it. The actuator bolts straight on. There is no bracket to work loose and no coupling to sit off-centre, which is where most small automated ball valves eventually fail.
Is the mounting pad a standard ISO 5211 pad?
Yes. It is not a proprietary fitting, so you are not locked into buying the actuator from us.
Can this valve throttle or modulate flow?
No. It is on/off only and we do not offer a positioner for it. A ball valve held part-way open drives the whole flow across one edge of the ball and one edge of the seat, and the PTFE will not survive it. If you need to modulate rather than shut, tell us what you are doing and we will tell you honestly whether we have the right valve.
What air pressure does it need?
4 to 8 bar.
Which actuator should I order — DA or SR?
Double acting if it is acceptable for the ball to stay where it is when the air supply fails. Spring return if the valve must land in a known position on air loss. Tell us which way it has to fail and we fit the matching cylinder.
What thread does it use?
PT, NPT or PF — all made to order. Tell us which when you ask for a quote.
What sizes is it available in?
3/8″ only. If you need a larger pneumatic ball valve, the two-piece V-2AM covers 3/8″–4″ with a full port and the same ISO 5211 direct mount.
Can I get the solenoid valve fitted as well?
Yes, and it is how most customers buy it. Our NAMUR solenoid bolts onto the actuator with no tubing between them, and the whole package ships assembled and tested.
Where is the dimension sheet?
There is no published dimension sheet for this valve yet. Email us and we will send you the dimensions and the actuator footprint.
Can I buy the valve without the actuator?
Yes. The valve is available on its own with the ISO 5211 pad, ready for the actuator you already use.
What is the working temperature?
Valve body −20 °C to +180 °C; the actuator −20 °C to +80 °C.
Do you have a minimum order quantity?
No. Tell us what you need and we will quote it.
