Abstract
A multiple opening sleeve valve is provided with a gate movable to control flow or pressure without the need for axial movement of a component through a pressure-containing seal. A gate actuator can include a drive rod and nut coupled to a gate substantially internal to the valve housing without the need for grease or similar external lubrication. The valve can provide for relatively high in-line gate-moving force, a reduction in force or torque requirements for operation, increased ease of wear-part replacement and decreased overall valve length, compared to previous valve configurations of comparable size or capacity.
