How To Operate A Butterfly Valve

How to Operate a Butterfly Valve.
A butterfly valve is an adjustable shut-off valve used in plumbing. When in the closed position it blocks water from reaching the other side of the valve. When turned to the open position it allows water to move past the valve. Using the butterfly valve requires you to adjust the top handle, which controls the overall water flow.

  1. Squeeze down on the handle at the top of the butterfly valve. This handle controls a circular device in the middle of the valve. When closed the circular device blocks the flow of water.
  2. Turn the handle clockwise to open the butterfly valve. This allows for the free flow of water.
  3. Squeeze the handle again, then turn it counterclockwise. This closes the valve, preventing water from flowing through
