Externally air-piloted 3/2 valves with single-pilot NC/NO or double-pilot control and M5 or 1/8 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.
3A110
Single air control; specify NC or NO
3A120
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 3A100 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 | M5 or 06=1/8; 06 threads: PT / G / NPT |
| Equivalent flow area / Cv | 10.2 mm² / 0.6 for 3A110-06 and 3A120-06 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 |

3A110-06-NO-G3AValve family
Published three-port two-position externally air-piloted valve.
1Series size
100 range.
10 / 20Pilot control
10 single pilot; 20 double pilot.
M5 / 06Port
M5 or 1/8 inch published port.
NC / NO; blank / G / TState and thread
10: NC normally closed or NO normally open. 20: no state suffix. M5: no thread suffix. 06: blank PT, G or T=NPT.
3A100 is the smallest published range in the 3A externally air-piloted three-port valve group. Its M5 and 1/8 port options, flow area and envelope are specific to this range; do not select it only because the circuit symbol looks similar to 3A200 or 3A300.
No. All are externally air-piloted three-port ranges, but technical specifications provide different port, flow and dimensional data for each. Match the complete code and installed interface.
No. NC and NO specify single-pilot 3A110. Double-pilot 3A120 has memory function and does not use that suffix. M5 has no thread suffix; 1/8 ports use blank PT, G or T for NPT.
Yes. Send a readable label or photos, the required circuit function, quantity and destination. We can help clarify single or double pilot, port and thread details before quoting.
