You can also perform performance restoration of the rotary valve and modifications for longer use.
Rotary valves are widely used for the transport of fluids due to the slowly rotating blades within a fixed housing. Powder enters the pockets of the rotating blades and is transported by the pressure difference before and after the piping. Although wear does not occur frequently due to the low rotation speed, it is still important to carry out repairs from the perspective of wear that can occur over many years at the fitting parts and other aspects beyond the usual wear of rotating machinery due to the characteristics of the transport principle. By consulting on issues such as stoppages caused by powder jamming and unstable transport behavior, as well as implementing modifications to the rotary valve for prolonged use, we achieve operational stability and cost reduction.
