Abstract
A rotating gate valve can be used to shear cables or tubing as it closes to obstruct flow. In embodiments, a valve body can have a flow passage and a lateral bore that is transverse to the flow passage. The gate can have a generally cylindrical shape and can rotate about the axis of the gate as it moves laterally to close a flow passage. The lateral and rotational movement can shear articles such as, for example, cables and tubing that extend through the flow passage.
