ΕΙΣΑΓΩΓΗ 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.

What is the Waterproof Rating of this valve? The motor's housing is rated at IP67 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? NO. This motorized ball valve is made of brass, which contains lead, should not be used for drinking water. 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 IP67 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 IP67. The 6 in IP67 represents complete dust - tightness. The 7 in IP67 indicates protection against water immersion up to 1 meter for 30 minutes. They are suitable for a variety of complex environments, effectively resisting the intrusion of dust and water to ensure reliable operation. WIRING SCHEMATICS Please note: 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.
