Response to I replaced my broken GVA-24. The new actuator works fine using the toggle switch. When my solar kicks on the valve moves counter clockwise 180 degrees which is good. When it turns off nothing happens. The actuator does not turn clockwise 180 degrees back to turn the flow of water off to the solar panels. I also have a brand new GL-235 controller and temp sensors. I have checked the temp sensors and they check out fine. Thanks for your help.
