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: Works great - Came fast, installed easy, works great.

## 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 – ½" NSF Certified 304SS threading, manufactured and measured according to National Pipe Thread (NPT) standards. This full-port electrical ball valve features a ½” bore, minimizing pressure loss through the valve, making it 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.

### ⭐⭐⭐⭐⭐ Solid Motorized Ball Valve- 1/2" Brass Ball Valve
*by T***E on October 5, 2025*

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.
