The present invention provides an actuated gate valve including a gate valve housing and an actuating device attached to one end of the gate valve housing. The gate valve housing includes a displaceable valve plate, and the actuating device includes an actuator rod connected to the valve plate so that a force applied to the valve plate by the actuator rod is coincident with a displacement of the valve plate.

What is claimed is: 1. An actuated gate valve, comprising: a gate valve housing comprising: two substantially identical housings, each identical housing having a recessed valve plate cavity portion, an additional cutout region positioned within the recessed valve plate cavity portion, said cutout region being a further recessed to capture debris and hold lubricant, and a semi-cylindrical actuator rod cavity portion, further recessed within the additional cutout region, the actuator rod cavity portion being disposed, at least in part, in the recessed valve plate cavity portion and in the additional cutout region, a fluid inlet, a fluid outlet, and a valve plate, slidingly disposed within the valve plate cavity, to regulate fluid flow through the gate valve housing; and an actuating device, attached to an end of the gate valve housing, having an actuator rod disposed within the actuator rod cavity portion and connected to the valve plate using a direct, in-line connection. 2. The actuated gate valve of claim 1, wherein the actuating device is a hydraulic actuator. 3. The actuated gate valve of claim 2, wherein the hydraulic actuator is removably attached to the end of the gate valve housing. 4. The actuated gate valve of claim 3, wherein the actuator rod is connected to the valve plate using a pin. 5. The actuated gate valve of claim 1, wherein the two identical housings are removably attached to one another. 6. The actuated gate valve of claim 1, wherein the fluid inlet and the fluid outlet are disposed on opposite sides of the gate valve housing and at an opposite end relative to the actuating device. 7. An actuated gate valve, comprising: a gate valve housing including a displaceable valve plate; and an actuating device, attached to one end of the gate valve housing, having an actuator rod connected to the valve plate to apply a force that is coincident with a displacement of the valve plate within the gate valve housing; wherein the gate valve housing is formed from two removably attached, substantially identical housings, each substantially identical housing having a recessed valve plate cavity portion, an additional cutout region disposed positioned within the recessed valve plate cavity portion. said cutout region being further recessed to capture debris and hold lubricant, a semi-cylindrical actuator rod further recessed within the additional cutout region and, cavity portion disposed at least in part in the recessed valve plate cavity portion, and a fluid opening disposed at an opposite end relative to the actuating device and wherein said actuator rod is disposed within the actuator rod cavity portion. 8. The actuated gate valve of claim 7, wherein the actuating device is a hydraulic actuator removably attached to the gate valve housing. 9. A method of assembling an actuated gate valve comprising: providing first and second substantially identical housing halves, each comprising a recessed valve plate cavity portion, an additional cutout region positioned within the recessed valve plate cavity portion, said cutout region being further recessed to capture debris and hold lubricant, a semi-cylindrical actuator rod cavity portion disposed at least in part in the recessed valve plate cavity portion and further recessed within the additional cutout region, and a fluid opening; placing an actuator rod in the semi-cylindrical actuator rod cavity portion of the first housing half connected to a valve plate positioned in the recessed valve plate cavity portion of the first housing half; securing the first and second housing halves together to form a gate valve housing assembly such that the recessed valve plate cavity portions form a recessed valve plate cavity and the semi-cylindrical actuator rod cavity portions form an actuator rod cavity; and attaching an actuating device to the actuator rod. 10. The method of claim 9 wherein the actuating device is a hydraulic actuator removably attached to the gate valve housing. 11. The method of claim 9, wherein said housing halves are cast.
