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 Reverse Polarity mode functions through a precise mechanism: To open the valve, connect the red wire to the positive terminal and the black wire to the negative terminal. Conversely, reversing the polarity will return it to the closed position. Disconnecting one or both wires will not alter the valve's state, it will maintain its current position.
The stainless steel ball valve is NSF certified, which means you can install it in the drinking water pipeline.

FAQ
1. What is the Waterproof Rating of this valve?
The motor's housing is rated at IP65 for ingress protection. If permanently installed outdoors, it is recommended to place it under a shelter or in a protective box to prevent prolonged exposure to rain.
2. What is the difference between N.C. (Normally Closed) and N.O. (Normally Open) ?
In a N.C. valve, it's closed without power and opens when energized. Conversely, in a N.O. valve, it's open without power and closes when energized, blocking fluid or gas flow.
3.What is the difference between Full Port and Standard Port?
In a full port valve, the internal diameter of the valve is the same as the pipe it's connected to. In a standard port valve, the internal diameter of the valve is smaller than the pipe size.
4.Can this be used for Drinking Water?
YES. The motorized ball valve is made of lead-free stainless steel and is NSF certified.
5.For auto return valves, what is the minimum On-Time required for electrical storage to enable closing when power off?
To ensure automatic reset functionality when the power is disconnected, it is essential to power the device for approximately one minute to charge the capacitor in 2-wire auto return motorized ball valves.
6.Can this valve be used for propane?
Yes, our motorized ball valves are suitable for use with propane.
WARNING
1. For 2-wire reverse polarity and 3-wire models, the valve is de-energized when fully open or closed. Other models may use a negligible amount of power when fully open, and the 5-wire model uses energy when closed to keep indicator lights operational. Refer to the specifications sheet for detailed information.
2.The valves depicted in this sheet are not designed to be operated manually. Attempting to manually open or close the valve may result in damage to the valve or injury.
3.Only Auto Return Models will return to the closed position in the event of a power outage. All other models will remain in their current position. If this is a concern, consider purchasing an Auto-Return Model.
4.While the motorized ball valves have an IP65 rating, making them resistant to water spray, it is recommended to enclose the valve in a protective housing if permanently installed outdoors to ensure long-term durability.
5.These valves are designed with power-limiting features, allowing them to be powered continuously without risk of overheating. However, always ensure proper installation and adherence to manufacturer guidelines to maintain safe operation.
Valve Attributes
Operating States:
Normally Closed: The valve is closed when power is off and opens when power is on.
Normally Open: The valve is open when power is off and closes when power is on.
Port Types:
Full Port: It has a wide internal passage, resulting in low water - flow resistance.
Standard Port: Meets regular usage requirements.
Ingress - Protection Rating:
The valves have an ingress - protection rating of IP65. The first digit 6 indicates complete dust - tightness. The second digit 5 means protection against water jets from any direction. They are suitable for a variety of complex environments, effectively resisting the intrusion of dust and water to ensure reliable operation.

Works the way it should
Nice little valve. Does what it should. Don't get the the kind that automatically close, they don't work as well. The reverse polarity is the way to go. Read more
Excellent Ball valve for the price, but it is not "U.S."
Very good product in our experience so far. We cycle tested one for 100,000 cycles, with the valve whetted. It was still running normally and still sealing in the off position. We are going to use these regularly. I like this powered open, powered close option. Inside, it has a microprocessor control circuit running a 5V motor and knows where to stop based on micro-switches. The "U.S." solid name seems to imply United States, but it is definitely not made in the United States. I doubt you could make these in the U.S. for twice the price. This is really a "China" Solid valve. That lack of truth in advertising is why I reduced 1 star.
