UV rated PVC ball valve

[KJM_WI_FL]

I need to replace a 1" and 3/4" PVC ball valve outside for water supply shut offs. The one supplied when the house was built is 7 years old and although the valve seems fine the handles are failing. I believe the Florida sun is to blame. Is there replacement meant for Exterior UV applications?

Metal valves are not hurt by the sun.
