OK, here's the walworth

The basic difference, as you can see now, is one seals against leakage using a force applied to a wedging action against the valve in a downward direction, the other seals by line pressure pushing the slab horizontally against the edge seal, I believe it has springs for secure sealing at low pressure. Call up the reps and they will be all too happy to come in and tell you the advantages of each.
I don't have experience with Walworth valves, but I can say M&J are good valves.

From anecdotal evidence (ie hearsay), wedge gate valves can get "stuck" more often than a slab gate. I am guessing that "gunk" can get into the bottom of the seat, and not allowing the wedge to seal tightly.

does wedge gate have top entry design?
becuase the slab gate desing has top entry design.

When the valve is being opened, the wedge moves up into the bonnet area. The line contents and pressure follow it. When the valve is closed, some contents and pressure remain in the bonnet area. The Stuffing (5) stops the contents & pressure from leaking. If the bonnet is removed by withdrawing bolts (6), there is open line pressure. The wedge will fly out. Major leak.
