Handle crack on diverter valve

[vlpronj]

I recently had a handle crack on my skimmer/bottom drain valve. Does it seem likely that I could find the replacement, unscrew the four screws on the top half, and replace just the top half, avoiding redoing the PVC joints? If so, can anyone tell me what brand (and maybe size?) this would be?

I'm not familiar with those valves. Maybe @jimmythegreek has seen them before and tell us if they are worth repairing.

Those valves look like jandy space saver valves but the handles are the Praher style. Look them up see if you can match it. They are rebuildable regardless no need to cut out
