Description
The electromagnetic reverser is piston driven and its function is to change the direction of the flow in oil or grease circuits in double line systems, the manoeuvre is carried out by means of two coils.
Design and operating principle
In the depressurization state, the piston (3) is kept in the central or rest position by the return springs (4). The piston (3) is operated by means of the solenoid (2). The magnetic force of the solenoid (2) acts through a pusher (5) on the piston (3) moving it from its resting position to the desired final position. In this way the desired flow directions are free, depending on the type of piston used. Once the solenoid (2) is depressurized, the piston (3) is moved again by the return spring (4) to its resting position.
The design of the arrangement of the connections follows the Cetop industrial standard that is given by flow capacity, therefore they must always be mounted on a secondary base of Nortek ref. 2012555.F10.
Note: To ensure proper operation, the solenoid pressure chamber must always be filled with oil.
Installation
It must be connected to a control panel and the reversion must be made through a final line pressure switch. The mounting system is stackable and allows multiple circuits to be made, minimizing the necessary space, saving assembly time and expensive pipe installations.
