The K type filling machine with EP electronic valve , which is newly developed and widely used by GrandPak, is suitable for filling carbonated and non-carbonated beverage products. In order to achieve the same filling consistency, the filling level is controlled accurately by retaining the muffler instead of using the level probe to control the filling level compared with the full-electronic filling valve, while ensuring high filling accuracy and high operation stability. The operation and maintenance are simple, with low operation cost , and the product quality is more guaranteed.
