What type of valve is this?

I need to replace this valve and I am having trouble finding out what type of valve that it is and what it does. Can anyone tell me what type of valve it is and what it does?

  • From what I can see it seems to have the manufacturers name and other specific details on it. Have you thought to do a Google search?
  • Examples of quarter-turn valves are ball valves, plug valves, and butterfly valves. There are 2 unmistakable kinds of direct valves: rising stem (multi-turn) and hub. While both valve types depend on the direct movement of the stream obstructed, they are altogether different in development and activity.
  • It is a vacuum breaker. It prevents the possibility of siphoning the tank contents back through the public water system should the public water system fail and result in negative pressure, which the chance of happening is less than hitting the lottery.

    They are great at failing to seal for reasons such as valve failure, or low water pressure which causes them to flood the area they're located in when you flush your tanks.
  • How do you know it needs replacing if you don't know what it is? Just a thought.
