Have mounted Jandy, Hayward, Pentair, Intermatic actuators with the included long screws that came with the actuator to every imaginable valve combination, including Waterway and CMP valves with never an issue. Just don't use power tools.You have pentair valves but you want to mount a 3rd party actuator to it without stripping/breaking the valve. Here is the part number for the long stainless screws:
CVA-SCRJ
(the screws in the bag are the short ones I took out of the valve)
