5. SYSTEM DESCRIPTION

5.1. General description

The direct-acting solenoid valve Type 6012 is available in two designs.

Type 6012 is used for the blocking, dosing, filling and venting of neutral gaseous and liquid media, in particular for controlling single-acting pneumatic actuators or technical vacuum. The modular designed valve can be installed individually or in a block on the multiple manifold.

Type 6012P is used as a special pilot valve for direct installation on the externally controlled pneumatic actuators. It consists of the magnetic actuator Type 6012 and a special connection body with hollow screw which can be connected directly to the control air connection of the actuator. The valve features manual actuation as standard.
