Principle characteristics DY series filling machine is a semi-automatic piston filling machine. A piston is driven by a cylinder to extract and eject materials, a one-way valve is used to control the flow of materials, and a magnetic reed switch is used to control the movement of the cylinder. The filling volume can be adjusted through the process. This machine has reasonable design, compact model and convenient operation. The pneumatic parts are all pneumatic components from Germany FESTO and Taiwan AirTac. The parts in contact with materials are made of 316L stainless steel, which meets GMP requirements. The filling volume and filling speed can be adjusted arbitrarily, and the filling accuracy is high. The filling head adopts anti-drip and lifting filling device
