A positioner/actuator mounted to the valve body has an output coupled to the actuator chamber to move the slidable plug with respect to the valve seat and thereby control fluid flow. In a single action device, a spring return moves the slidable plug towards the valve seat. In a dual acting embodiment, two actuating chambers are provided and two integral valve seats are provided in a symmetrical configuration. The valve seat is removable enabling different materials to be used for the valve seat.

  • Patent number: 6681792
    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.

  • Publication number: 20030196698
    Abstract: An axial flow control valve comprises a valve body having a flow passage containing therein a cylinder and an annular sleeve both are held in position by a positioning sleeve. The annular sleeve has a wall member formed with a multi-pores means for providing a number of V-shaped or elongate ports for reducing noise and vibration of fluid flow. A push rod is axially movably disposed within the cylinder, having one end attached with a resiliently biasing means for resiliently engaging a valve piston axially displaceable within the cylinder and the annular sleeve for controlling fluid flow. The positioning sleeve is formed with a truncated conical valve seat to associate with the valve piston for sealingly occluding fluid flow. O-rings made of resiliently metallic or ceramic material are disposed on the valve piston and/or the push rod for sealing the axially movable elements, so that the valve can be used in a high-temperature environment.

  • Patent number: 6571780
    Abstract: An air induction system (10) for use with an internal combustion engine (E) including an intake is disclosed. The system (10) includes a supercharger (12) and a valve assembly. The valve assembly comprises a valve (14) and a valve control mechanism (16). The supercharger (12) receives air through a supply opening (18), pressurizes it, and discharges it through an exhaust opening (20). The valve (14) is in communication with the supply opening (18) to control air supply thereto. The control mechanism (16) is coupled to the valve (14) and causes it to vary the air supply to the opening (18) in response to air pressure conditions downstream from the supercharger (12). In one embodiment, the control mechanism (16) varies the air supply responsive to air pressure in the intake in order to both throttle the supercharger (12) as well as substantially eliminate undesirable surge conditions therein.

  • Publication number: 20030075217
    Abstract: A valve is disclosed that is operable by converting rotational force of a stem into linear motion of a valve closure element, such as a sleeve, to control fluid flow through the valve. In a presently preferred embodiment, at least two interconnection members are rotatably mounted, such as with a round end, to a stem drive element. The interconnection members are slidably mounted into channels or grooves in a sleeve. Rotatable movement of the stem permits rotation of the interconnection members whereby the interconnection members are constrained to slide in the channels whereby rotational movement of the stem is converted into translational or linear movement of the valve closure element.
