SG-A Switching Device

The switching device SG-A with ram, enclosed consists of a housing with a metallically sealing piston, which is held in its mid-position by means of two compression springs. Furthermore, it consists of a limit switch, which is fixed in its position by means of a safety plate, on which these parts are fixed.

The switching device SG-A must be used in conjunction with the SA-V reversing valve. It is used as a differential pressure switch. When the differential pressure is 50 bar and/or 100 bar, the SA-V releases a pulse for the reversion of the directional control valve or for the monitoring of the system.
