ABSTRACT:
A hydraulically actuated device comprises a device body defining an inlet passage separated from an outlet passage by a first valve seat and a second valve seat, and a control passage that opens into an area between the first valve seat and the second valve seat. An essentially spherical ball valve member having a first radius of curvature is trapped between the first valve seat and the second valve seat. The inlet passage is fluidly isolated from the control passage by the ball valve member when the ball valve member is in contact with the first valve seat, and the outlet passage is fluidly isolated from the control passage by the ball valve member when the ball valve member is in contact with the second valve seat. An electrical actuator is attached to the device body. A pin is movable by operation of the electrical actuator to come into contact with and push against the ball along a curved striking surface of the pin having a second radius of curvature that is larger than the first radius of curvature.
