Abstract
A valve has an on-off control member disposed about an independently rotatable dynamic control member. The on-off control member, which interfaces with a sealing means, may be rotated to a closed position for shutoff purposes. Throttling operation is achieved by rotating the dynamic control member with the on-off control member in a stationary, fully open position which protects the sealing means. Bearings are placed between the dynamic control member and the on-off control member to permit the dynamic control member to rotate freely and accurately.
