Rotary valves are used for discharing and continous coveying. We develop many series of Rotary valves to meet different requirements: low pressure to high pressure, low temperature to high temperature, quick-cleaning, wear resistant. According to different mediums, in addition to the above form rotor, other forms such as: the arc bottom, flat, blade adjustable styles, in order to ensure the high life, high filling rate and smooth blanking. Different working condition need differet number of blades. The case and its main attachment are precision casting with good-looking appearance. The rotary valve with double outboard bearing, both strength and accuracy are improed. The bearing are protected by many rings to ensure long-time work. Wide square vent design reduces material discharge resistance and improves filling efficiency. Gear motor reductor drives and it's structure is compact. Our rotary valves are so efficient that even a smaller design will perform perfect. We make full use of materials to make the valve work economically.
