This patent describes a gate valve. It comprises a valve body having a valve opening therein, the valve opening defining an axis in a first direction; a first metal sealing means fixedly mounted to the valve body around the valve opening; a stationary frame fixedly mounted within the valve body; a moveable sub-frame moveably mounted on the stationary frame; a second metal sealing means moveably mounted on the moveable sub-frame, the second sealing means being mateable with the first sealing means, one of the sealing means being pressurizable to form a radial pressure seal with the other sealing means; valve actuation means connected to the moveable sub-frame to translate the sub-frame along the stationary frame in a second direction substantially perpendicular to the first direction; translation stopping means fixedly mounted in the valve body and positioned to stop the motion of the second sealing means in the second direction in a first position aligned with but spaced apart from the first sealing means as the sub-frame moves in the second direction; engagement forcing means on the sub-frame which in combination with the translation stopping means move the second sealing means in the first direction from the first position to a second position.
