3V solenoid valves switch three pneumatic ports between two positions. The range covers 100, 200, 300 and 400 body sizes, with single-coil and double-coil versions and nominal connections from M5 to 1/2″. Select the body, port size, control arrangement and coil voltage together.
| Body size | Single coil, code 10 | Double coil, code 20 | Port code | Nominal connection |
|---|---|---|---|---|
| 100 | 3V110-M5 | 3V120-M5 | M5 | M5 |
| 3V110-06 | 3V120-06 | 06 | 1/8″ | |
| 200 | 3V210-06 | 3V220-06 | 06 | 1/8″ |
| 3V210-08 | 3V220-08 | 08 | 1/4″ | |
| 300 | 3V310-08 | 3V320-08 | 08 | 1/4″ |
| 3V310-10 | 3V320-10 | 10 | 3/8″ | |
| 400 | 3V410-10 | 3V420-10 | 10 | 3/8″ |
| 3V410-15 | 3V420-15 | 15 | 1/2″ |
| Parameter | Specification |
|---|---|
| Working medium | Air filtered through a 40μm element |
| Pilot arrangement | Internal or external pilot |
| Valve function | Three ports, two positions (3/2) |
| Operating pressure | 0.15–0.8MPa |
| Proof pressure | 1.2MPa |
| Ambient temperature | -20–70°C |
| Body material | Aluminium alloy |
Proof pressure is a test rating and must not be used as the continuous operating limit. Specify the required pilot arrangement when ordering.
| Selection | Available choices |
|---|---|
| Body-size code | 1: 100; 2: 200; 3: 300; 4: 400 |
| Control code | 10: single coil, two positions; 20: double coil, two positions |
| AC coil voltages | 220V, 110V, 24V |
| DC coil voltages | 24V, 12V |
| Initial-state options | NC: normally closed; NO: normally open |
| Electrical connection | Plug type or lead-wire type |
| Thread options | G, PT or NPT for applicable threaded-port configurations |
For example, 3V210-08 AC220V selects the 200 body size, single-coil control, 1/4″ nominal connection and a 220V AC coil. Confirm the initial state, thread standard and connector arrangement for the required configuration; the voltage ratings are alternatives, not a universal-input coil.
The outline drawing below applies to 3V410-15 and 3V420-15. Both show three PT1/2 connections, a 34mm body width and two 5.2mm mounting holes. The illustrated overall lengths are 137.9mm for the single-coil valve and 193.8mm for the double-coil valve.
