Mechanically operated valves Series 1 and 3
Series 1: 3/2-way and 5/2-way, ports G1/8 and G1/4
Series 3: 3/2-way and 5/2-way, ports G1/8
Series 3: 3/2-way and 5/2-way, ports G1/8
These mechanically operated valves have been designed with three different types of actuation:
- plunger
- lever/roller
- unidirectional lever/roller
In each case, return is triggered by a mechanical spring.
3/2-way monostable valves Series 3 are normally closed in the rest position when pressure is supplied in 1 and are normally open when pressure is supplied on connection 3, the user port 2 remaining unchanged.
5/2-way valves Series 3 can be supplied via the ports 3 and 5 with two different pressures if a cylinder has to be operated using a delivery pressure which is different from the return pressure.
General Data
| Construction | Spool-type (Series 3), poppet-type (Series 1) |
| Valve group | 3/2, 5/2 way/pos. |
| Materials | Aluminium body, brass poppet, stainless steel spool, NBR seals |
| Ports | G1/8, G1/4 |
| Environmental temperature | 0°C ÷ 60°C |

| Fluid | Filtered air, without lubrication. If lubricated air is used, it is recommended to use ISO VG32 oil. Once applied the lubrication should never be interrupted. |
Coding Example
| 3 | 3 | 8 | – | 94 | 5 |
| 3 | SERIES 1 3 |
| 3 | FUNCTION 3 = 3/2 ways NC 4 = 3/2 ways NO (only Series 1) 5 = 5/2 ways |
| 8 | PORTS 8 = G1/8 4 = G1/4 (only Series 1) |
| 94 | ACTUATION 94 = Plunger 95 = Lever/roller 96 = Unidirectional roller |
| 5 | RESETTING 5 = Spring return |
