BrewBuilt Ball Valve with locking mechanism.  Locking mechanism is a safety feature that keeps the valve from being open by child or passing dog while you are brewing.  Easy to clean 2 piece design. High grade 304-stainless made to last. 1/2" FPT on input and output side.

TIP: You can take a ball valve apart using two crescent wrenches. This will allow you to open up the valve to get to the ball and the two PTFE gaskets that form the seal when closed.
