Abstract
A ball valve unit for shutting off the flow of fluids flowing in heating and plumbing systems. The ball valve unit includes a ball valve and a main section including a flange formed integrally with the main section. A chamber is formed in the main section for receiving the ball of the ball valve. The main section is made of brass in order to prevent galvanic action between ball valve unit and the heating/plumbing system.
