Question: Can a Jandy Valve or Valve Operator be used with the Goldline T-Valve?

Answer: All pool industry T-valves and valve operators that fit atop them are pretty much standardized and interchangeable. Some older valve operators use 12 volts a/c. All newer ones use 24 vac. The Goldline GL235 will allow you to use either voltage. See the Goldline technical manual for details.
