Diverter valves are used for directing the flow of bulk materials, perfect sealing and reliable switching are required for the convey system. We develop many series of diverter valves to meet different requirements: low pressure to high pressure, self-cleaning, divert with product, multi way. The case and its main attachment are precision casting with good-looking appearance. There are many types for different material. Smooth transition due to passage geometric design to reduce air resistance to a minimum. Perfect cylinder actuator can enhance automation level and operation reliability.
