Working Principle


Solenoid valves for weaving machines operate based on the electromagnetic effect1. When the coil is energized, it generates a magnetic field that attracts the valve core, changing its position1. This allows fluid (such as compressed air) to pass through the valve or be cut off, thus controlling the movement of certain components in the weaving machine1. For example, it can control the opening and closing of the warp shedding mechanism and the feeding and winding of the weft yarn.

Functions in Weaving Machines


  • Controlling Weft Yarn Tension: During the weaving process, the tension of the weft yarn needs to be maintained within an appropriate range. The solenoid valve, in conjunction with tension sensors and other components, adjusts the tension of the weft yarn by controlling the action of cylinders and other actuators.
  • Controlling the Opening Movement of the Weaving Machine: The weaving machine has an opening action during the weaving process, that is, controlling the up and down movement of the warp yarns to form the shed for the weft yarn to pass through. The solenoid valve can accurately control the relevant opening mechanism. According to the preset weaving pattern and process requirements, it controls the movement of the cylinder of the opening mechanism in a certain sequence, ensuring that the warp yarns are separated in the correct order and height, and the weft yarns are smoothly introduced.
  • Controlling the Warp Feeding and Take-up: The warp feeding mechanism needs to feed the warp yarns steadily, and the take-up mechanism should wind the woven fabric in a timely manner. The solenoid valve controls the start and stop of the warp feeding motor or adjusts the warp feeding speed, as well as controls the tension and speed of the take-up mechanism, ensuring the even density of the woven fabric and the continuity of the weaving process.
