Abstract
A rotary actuated gate valve for directing melt from a channel in a manifold to a mold gate includes a valve stem extending through and rotatable within the manifold. The valve stem includes a groove in fluid communication with the channel, wherein the groove is adapted to be rotated into alignment with the mold gate and channel for allowing the melt to flow into the mold gate. The groove is also adapted to be rotated out of alignment with the mold gate and channel for blocking the melt from flowing into the mold gate. The gate valve also includes a mechanism for rotating the valve stem. Another embodiment includes a rotatable housing having a groove, which operates in a manner similar to the valve stem design.
