The direct drive on a rotary valve is mounted directly on the shaft, providing maximum performance within a compact, streamlined, quiet, and cost-effective package.

Because Meyer’s 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.
