It adopts isobaric filling principle and filling valve adopts high precision mechanical valve. It has advantages of fast filling speed, high precision in liquid level and ensure that it only starts to filling when there is a can, otherwise it will stop. Using the device structure of filling valve precover device plus supporting can bottom device, it can guarantee the maximum stability of cans when they passing in and out. Filling cylinder braces use worm-gear box going up and down to satisfy cans of different height. Float switches in the filling cylinder ensure a smooth liquid inlet state.

The main transmission adopts gear transmission belt and gear box type exposed drive combination with advantages of higher efficiency, lower noise and smoother operation. It adopts frequency conversion stable speed regulation and is controlled by PLC industrial computers. Sealing machine and filling machine are connected by hooks coupling universal coupling to make sure they’re at same working pace. Host adopt advanced PLC automatic control technology, the key electrical components from famous company such as Japan's Mitsubishi, France Schneider, OMRON or ABB.
