The electromagnetic inverter is operated by a piston and its function is to change the flow direction in oil or grease circuits in double line systems, the maneuver is carried out by means of two coils.

Design and principle of operation

Directional valves are essentially made up of a body (1), one or two actuators (2), the control stem (3), and one or two return springs (4).

In the depressurized state, the control rod (3) is maintained in the central or rest position by the return springs (4). The control stem (3) is activated through the actuator (2). The magnetic force of the actuator (2) acts through a pusher (5) on the control rod (3) moving it from its rest position to the desired final position. In this way, the desired flow directions remain free, depending on the type of control rod used. Once the actuator (2) has been depressurized, the control stem (3) is again moved by the return spring (4) to its rest position.

The design of the layout of the connections follows the Cetop industrial standard, which is given by flow capacity, therefore, they must always be mounted on a secondary Nortek base ref. 2012555.F10.

Note: To ensure correct operation, the solenoid pressure chamber must always be filled with oil.
