Flow control/shut-off valve assembly

A flow valve assembly comprising:

• a supply line;
• a discharge line;
• a valve disposed between the supply line and the discharge line, the valve being operable between an open position and a closed position;
• a controller operatively coupled to the valve to operate the valve between the open position and the closed position;
• a flow detector operatively connected to the controller, the flow detector determining an amount of fluid flow through the valve when the valve is in the open position, wherein the controller operates the valve from the open position to the closed position when the amount of fluid flow exceeds a predetermined value;
• and
• a bypass assembly comprising:
• a first bypass three way valve in the supply line;
• a second bypass three way valve in the discharge line;
• and
• a bypass line providing fluid communication between the first bypass valve and the second bypass valve, the bypass line providing fluid flow around the valve;
• and
• a bypass flow meter in fluid communication with the bypass line and an audible alarm operatively coupled to the flow meter such that, when the fluid flows through the bypass flow meter, the audible alarm is activated.
