The high flow precision screw quantitative valve belongs to the medium displacement single component screw metering valve. The valve is driven by a Panasonic servo motor, which ensures uniform and stable dispensing, and can withstand pressure up to 1.5Mpa. There are two control modes: joint control and quantitative control. There is a glue calibration function and a suction function to prevent glue dripping and wire drawing. Suitable for dispensing, coating, and filling small amounts of glue, especially suitable for dispensing and coating medium high viscosity media such as silicone sealing strips and thermal conductive mud, as well as high flow filling of medium low viscosity.
