The brass solenoid valves from NieRuf are particularly suitable for water applications and water treatment plants, e.g. in industry. But they are also used lots in machine and plant construction. Because of the large number or possible applications, there is also a large number of different valves. In the voltage area, we are able to offer valves in with 24V, 110V or 230 V. These valves have an internal thread and are available in the nominal widths 1/8" - 2" inches. Depending on the desired switching function, these are available as NO (normal open) or NC (normal closed). Some of the valves have ATEX approval. In addition, depending on the model these are directly controlled, forced controlled or servo-controlled.
