Our rotary airlock valves are used in a wide range of applications where there is need to minimize system air loss while transferring material between vessels with differing pressures. They are used as feeder valves to meter the flow of material between vessels with equivalent pressures. You will also find them doing double duty in systems where there is a need to minimize system air or gas loss while regulation the flow of material between vessels with differing pressures. You can count on Meyer to bring the right solution to your specific needs.
