Have you ever been troubled by unexpected pipe leaks?

Burst pipes, seeping valves, costly repairs…

Household water safety should never be compromised by “small leaks.”

Leak-Proof Design Highlights:

The W22 Water Leak Protection Controller is equipped with a stainless-steel metal probe that can accurately detect leakage. Once water leakage is detected, it instantly triggers an alarm and automatically closes the valve. With waterproof quick-connect terminals and a fully sealed, moisture-resistant design, the controller ensures superior stability and reliable operation.

Valve Specifications:

Available in DN8–DN50 sizes, the valve adopts a full-bore ball valve structure, featuring low flow resistance and excellent sealing performance. Whether for daily water use or emergency shut-off, it delivers “one-valve control, zero leakage.”
