Abstract

A tank tee assembly includes a tank tee body including a tank tee inlet, a tank tee outlet and a tank tee passageway therebetween. The tank tee body also includes a first tank leg having a first tank leg passageway disposed in fluid communication with the tank tee passageway intermediate the tank tee inlet and tank tee outlet. The tank tee assembly also includes a ball valve assembly including a valve body including a valve inlet, a valve outlet and a valve passageway therebetween. A ball element is disposed within the valve passageway. A ball valve seat is disposed within the valve passageway between the tank tee outlet and the ball element. The valve inlet is in threaded engagement with the tank tee outlet such that the tank tee body urges the ball valve seat into sealing engagement against the ball element.

a first tank leg having a first tank leg passageway disposed in fluid communication with the tank tee passageway intermediate the tank tee inlet and tank tee outlet; and

a poppet valve assembly disposed in the tank tee passageway, the poppet valve assembly including a poppet moveable between a closed position and an open position; and

wherein when the poppet is in the closed position a flow of fluid from the tank tee inlet to the tank tee outlet is inhibited, and when the poppet is in the open position the flow of fluid is allowed.

11. The tank tee assembly of claim 10 comprising:

an annular flange disposed on a peripheral surface of the tank tee passageway, the annual flange having a poppet valve seat;

the poppet valve assembly including;
