ZITA BG ELECTROMAGNETIC (SOLENOID) VALVE Type 0955503.0900 Normally closed; indirect effect; G 1; 2/2 way PRINCIPLE OF OPERATION The electromagnetic valves of this type are devices providing by means of electromagnetic drive control of flowing and stopping of fluid on the pipelines. In the automatic regulation systems they serve as relay bodies for remote control and regulation. The electromagnetic valves are intended for integration in automatic systems in machine building, energy, chemical industry etc. The electromagnetic valves of these series are two-way, twopositioned, normally closed, with indirect effect. The valves have a certain direction of fluid flow, which is indicated on the article. Many of the electromagnetic valves are operating on digital principle. Because of this they have two states – when to the electromagnet (coil) is supplied electrical signal and when the valves are in idle state (no voltage is supplied). The valves function is determined of their state in which they are at the moment.
