This NPT 1/2 brass motorized ball valve is affordable enough for the home hobbyist, while durable enough for titans of industry. The valve body and stem are made of strong brass.It actuates using 9V to 24V of AC or DC power, and will fully open or fully close in 3-5 seconds. Once in position, it automatically stops using energy. This is important as it will never overheat. This is a key difference between motorized ball valves and solenoid valves. Most solenoid valves are constantly energized, while these electrical ball valves are not, making them safer and more eco-friendly. The casing is rated as IP65. (6) represents a seal that protects against all solids, even dust. For water, the rating (5) represents seal protection against water spray from all directions. This means the casing and body are all built to last. Motorized ball valves have a variety of interesting and convenient uses. Many choose to use them in home water systems. They are also a great tool for use in home automation projects.
Lastly, all of the U.S. Solid motorized ball valves work well with Arduino automation systems.The Position Indicator on the top of actuator can help you see the on / off state of the valve. In addition, the valve comes with manual function, it can be adjusted manually if the valve is locked. Or when the power is cut off, the valve can be opened manually if necessary.
