A high-pressure gate valve for control of bulk materials includes a main body with an opening for passing bulk material, an upper body, a slideable blade, and lifting structure configured to raise the blade in a planar motion, perpendicular to the primary direction of travel and seal it against the upper body when the blade is extended. An actuating cylinder coupled with a rear edge of the blade extends and retracts the blade. A rear portion of the valve is enclosed to protect the rear edge of the blade, the actuating cylinder, and the coupling between the two. |
