Review: Pricey but solid. - Pricey but solid. they work solid and do make the zippy noise. These are not INSTANT. They take a couple of seconds to open or close. Great for RV tanks as you can barely hear them work. I haven't had one malfunction yet with gray water or debris. I got them on multiple tanks under the RV for almost a year, no problems (I do spray silicon lubricant into each valve every 6 month to avoid salt water corrosion). These don't overheat when left ON ( I leave them open all night when the temp drops below freezing) to empty the tanks and avoid ice damage.
Review: Solid Motorized Ball Valve- 1/2" Brass Ball Valve - I used this to control the water for an automatic evaporative cooler setup. It worked perfectly all summer exposed to full sun in 115°+ weather. It did not see much rain so I cannot confirm its water resistance.

## Features

- SAFE AND RELIABLE – Made from SS304 NSF Certified 304SS and NSF certified, this ball valve is safe for drinking water. It has a lifespan of 80,000 to 100,000 cycles.
- NPT THREADING – ¼" NSF Certified 304SS threading, manufactured and measured according to National Pipe Thread (NPT) standards. This standard-port electrical ball valve features a bore slightly less than ¼”, minimizing pressure loss—ideal for home automation projects.
- 9V-24V AC/DC – Operates effectively across the entire voltage range; opens or closes the valve in 3-5 seconds. The limit switch reduces power consumption once the valve is fully open, making it ideal for projects requiring automatic return.
- 2-WIRE AUTOMATIC RETURN SETUP – Simple two-wire connection; the valve largely de-energizes after opening and returns to fully closed if power is removed.
- ALTERNATIVE TO SOLENOID VALVES – Automatically cuts off power once fully open or closed, reducing the risk of overheating. Ideal for projects requiring a valve to remain open for extended periods. OUTDOOR INSTALLATION TIP – If permanently installed outdoors, it is recommended to place the valve under a shelter or inside a protective box to prevent prolonged exposure to rain.

## Questions & Answers

**Q: What is the Waterproof Rating of this valve?**
A: 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. For more details, please refer to Picture 1.

**Q: What is the difference between N.C. (Normally Closed) and N.O. (Normally Open) ?**
A: 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. For more details, please refer to Picture 2.

**Q: What is the difference between Full Port and Standard Port?**
A: 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. For more details, please refer to Picture 3.

**Q: Can this be used for Drinking Water?**
A: YES. The motorized ball valve is made of lead-free stainless steel and is NSF certified.

**Q: For auto return valves, what is the minimum On-Time required for electrical storage to enable closing when power off?**
A: 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.

### ⭐⭐⭐⭐⭐ Reliable and Easy to Use​
*by L***M on April 17, 2025*

Installed this valve in my home automation setup, and it's been working flawlessly. The auto-return feature is great—when the power cuts, it closes automatically, which adds peace of mind. The stainless steel build feels solid, and the full port design doesn't restrict flow. Wiring was straightforward, and it operates quietly. Highly recommend for anyone needing a dependable motorized valve
