On vertical air ducts, the electrically operated valve can also be installed in any position. On horizontal air ducts, the electric actuator must be located in the upper hemisphere relative to the horizontal plane, with the valve shaft positioned above the air duct axis.<\/p>\n<p>During opening, the actuator rotates the disc connected to it by a shaft. At the beginning of the shaft\u2019s rotation, when it reaches approximately 10\u201320\u00b0, the disc moves away from the seat in the valve body with the help of springs. As rotation continues, the disc aligns parallel to the valve passage axis and fully opens the air passage.
