Introduction
Motorized ball valves are a vital piece of equipment in numerous applications. This model opens and closes in 3-5 seconds, and remains in its new position while expending almost no energy. This is a key difference between motorized ball valves and many solenoid valves. Most solenoid valves are energized continuously when in a new position, while motorized ball valves expend energy only when changing from open to close, or vice versa.
The 2 wire auto return model is perfect for situations where the valve needs to be closed in case of power loss. The valve can be energized to open, and left hooked up, with negligible energy used once fully opened. To close, simply shutoff power to the valve. This valve is convenient because it can be operated with a simple on off switch. When on, it will remain open, when turned off (or power is lost for some other reason) the valve automatically closes.
