Even the Rotary Valve Piston Filler is able to suck directly from a source tank through pipes. With regard to its working, in the first stage, the rotary valve is fed with the material from the hopper due to the movement of T-shaped cylinder/syringe. Then the valve takes a flip of 90 degrees and connects the syringe/cylinder with the nozzle for proper dispensing of material, disconnecting itself from the hopper. Thus at one time, the high-quality valve connects only two pieces of equipment to ensure the seamless filling. Products Which Can Be Filled:
