The Meyer HDX comes in various drive options, round or square flange, and 14 sizes. Permanently sealed bearings ensure protection from contamination.
The direct drive on a rotary valve, as the name implies, is mounted directly on the shaft, providing maximum performance within a compact, streamlined, quiet and cost-effective package.
Because Meyer’s new HDX direct drive rotary airlock valve has fewer components, it is not only easier to install but it reduces maintenance by eliminating side-mounted sprockets and chain. The direct drive is also 5% more efficient than a chain drive, eliminating mechanical losses.
With no exposed rotating shaft, the valve in operation is inherently safer, eliminating pinch points and the need for chain guards.
An additional benefit is the ability to easily change the speed of rotation when paired with a variable speed controller. Typical ratios are 10:1 with special designs to 20:1.
