Roto-Disc, located in Erlanger, Kentucky, has recently introduced airlock/double-dump valves that are now capable of feeding and measuring product into and/or out of pressure or vacuum environments, in four modes.
Through the development of the RDCC Cycle Timer and enhancements to its accumulator chambers, applications now have volumetric and gravimetric measuring capability, in addition to traditional temporal and manual control. Included in this new capability is the option to switch between any of these modes almost instantaneously and then return to operation just as quick, providing measurement flexibility.
The new feeding solutions are accomplished with load cell mounts and/or level sensor ports, both of which are located on the chamber according to the application requirements. Gravimetric solutions are provided with flexible connections on the assembly for accurate weight measurement.
