A high-pressure gate valve (10) for control of bulk materials includes a main body (12) with an opening (18) for passing bulk material, an upper body, a slideable blade (42), and lifting structure configured to raise the blade (42) in a planar motion, perpendicular to the primary direction of travel and seal it against the upper body when the blade (42) is extended. An actuating cylinder (52) coupled with a rear edge (76) of the blade (42) extends and retracts the blade (42). A rear portion (16) of the valve is enclosed to protect the rear edge (76) of the blade (42), the actuating cylinder (52), and the coupler (56) between the two. |
