Solenoid actuated valves
series L1/L2 |
|
Popular series of solenoid pilot actuated valve, which off ers high flow capacity and long lifetime due to robust coil. Valves can be used as standalone or they can be mounted on manifolds. Valve can be delivered with position sensing switch on request. Valves series L1/L2 contains spool and sleeve assembly, which guarantee long lifetime of valve. |

Conversion of internal to external air pilot supply of valve series L1 / L2:
External air pilot supply is used, when air supply pressure is lower than 0,18 MPa (1,8 bar) as well as for vacuum and or if another medium than compressed air is used. It is necessary to order valve which is already prepared for this feature or change standard setting (when air pilot supply is drawed from valve supply port 1) in that cases.
When converting from internal to external pilot supply, please proceed as follows: | ||
1) Unmount connector |
