LARGE VALVES – 2.25" Diameter. May have a T-Handle Release, 1/4" Nut Release, or a Cam Release.

T-Handle Release –

  • Turn the T-handle counterclockwise to open the valve. The T-handle should turn easy at first and then meet some resistance as it compresses a spring. The T-handle will have to turn approximately 4 ½ full turns to fully open the valve.
  • When closing the valve, the T-handle only has to be snug. Do not over tighten.

1/4" Nut Release –

The nut release is located under a plastic cap in the center of the valve between the two wires.

  • Remove the cap.
  • Use a ¼” nut driver to turn the nut counterclockwise. DO NOT turn the nut more than 2 full turns. Turning the nut more than 2 turns will damage the valve.
  • When closing the valve, the nut release only has to be snug. Do not over tighten.
  • Replace the plastic cap to keep debris out of the valve.
