1/2 in. (12.7 mm) Ball Drip Valve NPT provides a reliable defense against system damage and dysfunction caused by expanding ice in water-based systems, including fire sprinkler and standpipe systems.
Featuring a durable and corrosion-resistant brass bonnet, ball, and body, this gravity-operated 1/2 in. (12.7 mm) Ball Drip Valve drains the lowest system point between a Fire Department Connection (FDC) and check valve.
When properly installed, the valve closes under pressure and prevents leaks during system activation. Gravity returns the ball to the open position as water flows stop.
This 1/2 in. (12.7 mm) Ball Drip Valve uses the same National Pipe Thread (NPT) found in plumbing, fire prevention, and industrial piping systems throughout the United States.
