Max. number of valves

The maximum number of electric valves that can be simultaneously connected to the control unit; in other words, the largest number of points at which the water supply can be shut off using this system. For home use, most often 2–3 taps are sufficient (hot water, cold water, washing machine/dishwasher); for larger buildings, a larger number may be required.

Closing time

The speed of the valve responds to an alarm signal. The faster the valve closes, the less water will spill from the depressurized circuit. A good response time is 2.5 s. For entry-level and mid-level leak protection systems, the normal response time is 5 to 7 seconds.
