摘要: A valve having improved inherent flow characteristics, noise and dynamic torque characteristics is provided. The includes a disk for controlling fluid inside the valve. has first vane second disposed relative to vane. In accordance with one embodiment, along an axis extending from pivot point of disk. such offset can be substantially parallel. further upstream indentation reduction include cavitation reducing features on downstream side and/or in case reversal.
