Turn the blue handle to open or close the water supply. The wide handle gives the user a firm grip and makes operation simple, even when the valve is installed close to the wall. This quick control is convenient when the water heater supply needs to be turned off for cleaning, inspection or connection work. The wall inlet feeds water into the angle body, and the threaded outlet directs the connection downward. This layout reduces projection into the surrounding area and keeps the connected line in a clear vertical position. The large-flow design supports a strong and smooth water output for the connected line. The valve is made of brass and has a 4 Fen inner diameter. It uses a rotary threaded installation and works under normal pressure. The blue handle stands out clearly against the bright metal body, making the control easy to identify around the water heater. OEM and ODM customization is available for wholesale and project orders.
