I had some good success with using Liquid Wrench silicone spray on the valve stems of old, sticky PVC valves. I removed the valve handles, sprayed around the stem, then opened the filter vent to create some vacuum....don't know if that helped, but better than pressure. I cycled the valves a few time, let things sit for 30 minutes with pump off, then cycled again. The rotating effort was significantly reduced and they now rotate stop to stop.

Ball valves inevitably get hard to turn and stuck over time. Bets thing you can do is exercise them often to try and prevent sticking. Don't try and force the valve too much or the handle will break off. Some ball valves are repairable and others are not.

When the ball valves are getting hard to turn it is best to replace them with diverter valves.
