The stem-rising metal-sealed gate valve raises and lowers the valve flap through the threaded rotation of the stem and the steering wheel. The gate valve lifting screw is exposed, with the nut allowing for handwheel operation. The nut is fixed, and by rotating the screw, the gate plate is lifted. The screw and the gate plate have only relative rotational movement, with no relative axial movement, giving the appearance of a gate-shaped bracket.
