With 1 small issue. - I've had about 5 of these pumping antifreeze for years. Thousands and thousands of gallons without fail. This will be the first replacement, and it isn't really even the fault of the valve. They have an issue with water intrusion if used in open air, it may take 5 years but it will happen. Solution? Drill a tint hole under the motor to allow any water to escape. Also, seal the top with a tiny bead of RTV. If you do that there is no reason this valve left outside, shouldn't last 10yrs+. Review: Well made and easy to install - I needed to automate the flush valve our our sediment filter, to open for one minute once a week. Since there was a sprinkler timer nearby I needed a value that was energized to open and automatically closes when deenergized. And because of the large amount of sediment in the flush water I needed a ball valve instead of a solenoid valve. So this particular valve is perfect. I opens quickly when actuated from a standard sprinkler controller, and closes reliably when the sprinkler controller removes power. It has standard 1/2" pipe threads and installs easily. It's worth noting that this valve does not have a way to manually activate it, but I can use the manual mode of the sprinkler controller for that. It's only been installed a few weeks, but so far it's running perfectly. ## Features - NSF CERTIFIED 304 STAINLESS STEEL: Built with NSF Certified lead-free 304 stainless steel metal components that resist corrosion and ensure safe drinking water for potable water lines, home brewing, and food-grade fluid transfer - FULL PORT AND HIGH PRESSURE: Full-port bore with an 8 mm flow aperture matches pipe size for unrestricted flow; PTFE seats and silicone seals handle working pressures up to 1.0 MPa (145 psi) through a compact 1/4 in NPT body - WIDE 9-24 V AC/DC OPERATION: Compatible with AC or DC power across 9-24 V; opens or closes in 3 to 5 seconds, and an internal limit switch cuts power at end of travel to eliminate heat buildup and lower energy consumption - 2-WIRE AUTO RETURN NORMALLY CLOSED: Simple 2-wire hookup drives the valve open when energized and automatically returns it to the closed position the moment power is cut for reliable automated line isolation - IP65 RATED SOLENOID ALTERNATIVE: IP65 enclosure seals against dust and water spray; rated for 80,000 to 100,000 cycles with zero holding current to stay cool during long runs in irrigation, HVAC, and RV plumbing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XXPZHVB | | Best Sellers Rank | #10,175 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #21 in Ball Valves | | Brand | U.S. Solid | | Brand Name | U.S. Solid | | Connector Type | Threaded | | Customer Reviews | 4.5 out of 5 stars 550 Reviews | | Exterior Finish | Stainless Steel , Steel | | Inlet Connection Size | 1/4 inches | | Inlet Connection Type | National Pipe Tapered | | Item Dimensions | 3.35 x 2.68 x 2.28 inches | | Item Weight | 0.26 kg | | Item dimensions L x W x H | 3.35 x 2.68 x 2.28 inches | | Manufacturer | U.S. Solid | | Manufacturer Part Number | USS-MSV00027 | | Material | Stainless Steel | | Material Type | Stainless Steel | | Maximum Pressure | 1000 kilopascal | | Model Number | USS-MSV00027 | | Number of Items | 1 | | Number of Packs | 1 | | Number of Pieces | 1 | | Number of Ports | 2 | | Outlet Connection Size | 0.25 inches | | Outlet Connection Type | NPT | | Size | 1/4 Inch | | Specification Met | nsf certification | | Thread Size | 0.25 inches | | Thread Type | NPT | | UPC | 888107083504 | | Unit Count | 16 Ounce | | Valve Type | Ball Valve | ## Product Details - **Brand:** U.S. Solid - **Exterior Finish:** Stainless Steel,Steel - **Inlet Connection Size:** 1/4 Inches - **Inlet Connection Type:** National Pipe Tapered - **Item dimensions L x W x H:** 3.35 x 2.68 x 2.28 inches - **Material:** Stainless Steel - **Maximum Operating Pressure:** 1000 Kilopascal - **Number of Ports:** 2 - **Outlet Connection Size:** 0.25 Inches - **Outlet Connection Type:** NPT ## Images ![1/4 in Motorized Ball Valve, NSF Certified 304 Stainless Steel Electric Valve, Normally Closed, 9-24V AC/DC, 2-Wire Auto Return, Full Port - Image 1](https://m.media-amazon.com/images/I/51+IfxnK-CL.jpg) ![1/4 in Motorized Ball Valve, NSF Certified 304 Stainless Steel Electric Valve, Normally Closed, 9-24V AC/DC, 2-Wire Auto Return, Full Port - Image 2](https://m.media-amazon.com/images/I/513cGKLskSL.jpg) ![1/4 in Motorized Ball Valve, NSF Certified 304 Stainless Steel Electric Valve, Normally Closed, 9-24V AC/DC, 2-Wire Auto Return, Full Port - Image 3](https://m.media-amazon.com/images/I/51+Qcd2+RiL.jpg) ![1/4 in Motorized Ball Valve, NSF Certified 304 Stainless Steel Electric Valve, Normally Closed, 9-24V AC/DC, 2-Wire Auto Return, Full Port - Image 4](https://m.media-amazon.com/images/I/61WH2jPFyWL.jpg) ![1/4 in Motorized Ball Valve, NSF Certified 304 Stainless Steel Electric Valve, Normally Closed, 9-24V AC/DC, 2-Wire Auto Return, Full Port - Image 5](https://m.media-amazon.com/images/I/51ONXM-X5ZL.jpg) ## Available Options This product comes in different **Color, Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic valves. With 1 small issue. *by R***J on October 12, 2025* I've had about 5 of these pumping antifreeze for years. Thousands and thousands of gallons without fail. This will be the first replacement, and it isn't really even the fault of the valve. They have an issue with water intrusion if used in open air, it may take 5 years but it will happen. Solution? Drill a tint hole under the motor to allow any water to escape. Also, seal the top with a tiny bead of RTV. If you do that there is no reason this valve left outside, shouldn't last 10yrs+. ### ⭐⭐⭐⭐⭐ Well made and easy to install *by C***Y on September 4, 2023* I needed to automate the flush valve our our sediment filter, to open for one minute once a week. Since there was a sprinkler timer nearby I needed a value that was energized to open and automatically closes when deenergized.

I have connected several of these (indoors) to cheap basic Wi-Fi Wireless Smart Switches that link to Alexa, and now I can turn on spigots and set water timers from anywhere. I put a 5th gen Echo Dot (has built-in thermometer and now allows tasks based on temperature) in my barn, and created a routine that any time the temp falls below 36 the water to the barn turns off inside the house; and the water lines in the barn open to drain their water. I can turn on the water to my cattle trough and just say as I leave the barn "Alexa turn off cattle trough water in 15 minutes" and she does. Same with water sprinklers, etc. ## Frequently Bought Together - U.S. Solid Motorized Ball Valve- 1/4" Stainless Steel Ball Valve with Full Port, 9-24V AC/DC and 2 Wire Auto Return Setup - Wireless Light Switch and Receiver Kit, 30A High Power, No Wiring, 984ft RF Range,AC110V/120V220V Remote Control Switches ralay for Lamp, Motor,Ceiling Light, Fan, Outdoor Lighting - HiLetgo Latching Pushbutton Switch 16mm 5/8" 12V-24V 5A Power Angel Eye LED Light Metal Toggle Switch with Wire Socket Plug --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/77515936-1-4-in-motorized-ball-valve-nsf-certified-304-stainless](https://www.desertcart.sn/products/77515936-1-4-in-motorized-ball-valve-nsf-certified-304-stainless) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-02*
