The electrovalve has a body (1) with a longitudinal flow line (2), and a magnetic coil (3) with a roller core (4). The core forms a short-circuiting device moved in a back and forth movement. Length of the core is provided in such a manner that the core releases entire diameter of the line in an open position of the electrovalve and does not release the entire diameter of the line in a closed position. Distance of ends of the core from coil winding borders is less than half of length of the coil. An electronic end switch (8) is placed at both ends of a channel (7) on the body. |
