Take Full Control of Your Water & Gas — From Anywhere
The eWeLink WiFi Smart Automated Ball Valve brings intelligent automation to your home's water and gas lines. Available in DN15 (1/2"), DN20 (3/4"), and DN25 (1") sizes, this CE-certified smart valve lets you open or close your water or gas supply remotely via the eWeLink app, voice commands, or scheduled timers — giving you peace of mind whether you're at home or away.
Made in Mainland China.
Why Choose a Smart Ball Valve?
Water and gas leaks are among the most costly and dangerous home incidents. A smart shutoff valve lets you act instantly — even when you're not home — to prevent flooding, gas buildup, or appliance damage. Learn more about home water safety from the CDC's Healthy Water emergency resources.
