First claim

Opening claim text (preview).

What is claimed is: 1. A gate for a gate valve, the gate comprising: a first disc-shaped side; and a second disc-shaped side, wherein the first disc-shaped side includes a first center guide and a first diameter, the first center guide being a convex ridge extending along the first diameter and including a longest outward extension of the gate as measured perpendicularly from a face of the first disc-shaped side. 2. The gate of claim 1 , wherein the second disc-shaped side includes a second center guide and a second diameter, the second center guide being a convex ridge extending along the second diameter. 3. The gate of claim 1 , wherein the first center guide extends along the first diameter entirely. 4. The gate of claim 1 , further comprising a circumferential side defining a circumference, a first circumferential endpoint, a second circumferential endpoint, and two circumferential midpoints, the first circumferential endpoint being at a first intersection of the first diameter and the circumference, the second circumferential endpoint being at a second intersection of the first diameter and the circumference, the first and second circumferential midpoints each being half way between the first and second circumferential endpoints, the circumferential side extending in a continuous curve through the circumferential midpoints. 5. The gate of claim 4 , wherein the circumferential side at the first and second circumferential midpoints defines the radially outermost surface. 6. The gate of claim 1 , wherein the first disc-shaped side includes a first width and the convex ridge includes a second width, the second width greater than the first width. 7. The gate of claim 1 , wherein the convex ridge extends along an entirety of the diameter of the first disc-shaped side. 8. The gate of claim 1 , further comprising a stem having a first center axis, the first center axis being parallel to the first diameter. 9. The gate of claim 1 , wherein the convex ridge extends across a center of the first disc-shaped side. 10. The gate of claim 1 , further comprising a second convex ridge extending along a diameter of the second disc-shaped side.
