Mechanically operated sensor valves Series 3 and 4
3/2 and 5/2-way
Ports G1/8, G1/4
Ports G1/8, G1/4
The particular mechanical device allows these end-stroke valves to operate with very low actuating forces.
Series 3 has been designed with a mechanical lever device which works in negative pressure. To increase sensitivity it is possible to add to the lever a steel extension with Ø3 mm.

Coding Example
| 3 | 3 | 8 | – | D15 | – | 9A5 |
| 3 | SERIES 3 4 |
| 3 | FUNCTION 3 = 3/2-way NC 4 = 3/2-way NO 5 = 5/2-way |
| 8 | PORTS 8 = G1/8 4 = G1/4 |
| D15 | ACTUATION D15 = Pressure drop/spring 015 = Pressure/spring 011 = Pressure/pressure |
| 9A5 | DEVICES 9A5 = Lever sensor, spring return 194 = Plunger sensor, spring return 294 = Plunger sensor, bistable 195 = Lever/roller, spring return 295 = Lever/roller, bistable |
