Externally air-piloted 3/2 valves with single-pilot NC/NO or double-pilot control and 1/8 or 1/4 main ports. Send your model or label with quantity and destination for a quotation.
Know your model? Send it with the quantity for a quote. Not sure? Start with a photo, label or description. We help identify the model and clarify availability and lead time. Mixed parts lists are welcome too.
Choose a type; send a model or photo if unsure.
3A210
Single air control; specify NC or NO
3A220
Double air control; memory function, no NC/NO suffix
Send the model, quantity and destination. For multiple items, attach a parts list or BOM.
Match a 3A200 model code
1–16 stations; request the base alone or a valve assembly. The base inlet (100M/200M: 1/4; 300M: 3/8) is separate from the selected valve main port. Send the model, thread, occupied stations and required contents.

Helpful for Model Matching:
| Valve function | 3 ports / 2 positions; external air pilot |
| Control | 10: single pilot NC/NO; 20: double pilot, memory function |
| Main ports | 06: 1/8; 08: 1/4 inlet/outlet; blank PT / G / T=NPT |
| Equivalent flow area / Cv | 17.0 mm² / 1.0 for 3A210-08 and 3A220-08 only; calculated from flow tests |
| Operating pressure | 0.15–0.8 MPa (21–114 psi) |
| Proof pressure | 1.2 MPa (175 psi) |
| Temperature | −20 to +70 °C |
| Air / lubrication | Air filtered through 40 μm element; lubrication not required. Once lubricated, continue using the same medium; ISO VG32 or equivalent recommended. |
| Maximum frequency | 5 cycles/s at no-load state |
| Body | Aluminum alloy |

3A210-08-NO-G3A2Valve family / size
3/2 externally air-piloted valve, 200 range.
10 / 20Control
10 single air pilot; 20 double air pilot with memory function.
06 / 08Main ports
06: 1/8 inlet/outlet; 08: 1/4 inlet/outlet.
NC / NORest state
10 only: normally closed NC or normally open NO; 20 has no state suffix.

Blank PT; G=G; T=NPT.
3A200 is the mid-size published 3A range. Its 1/8 and 1/4 port forms and drawing set are not interchangeable with 3A100 or 3A300.
Confirm the 10 or 20 pilot control, installed 1/8 or 1/4 port, NC/NO state where applicable, thread and base/interface. Port size alone is not enough.
The official accessory catalogue lists 3V200M for 3A200, with 1–16 stations and a 1/4 base inlet. Send the valve models, occupied stations, base thread and required blank plates. Use the 3A assembly drawing for installed clearance.
Yes. Send the label or photos, circuit function, quantity and destination. Single-pilot codes need NC or NO; double-pilot codes use neither. We can help clarify the remaining details.
