Water leak detectors with valve and control unit

Valve with control unit

— separately sold ball valves with built-in control units.

In general, it makes sense to buy separate components in two cases: if you want to assemble the system at your discretion, without relying on ready-made kits, or if the device is purchased to replace an old one that has failed. The purpose of the control unit is already clear from the name, and the ball valve (with electric drive) is used to shut off the pipeline when the leakage sensor is triggered. In this case, the valve and the control unit are combined in one device.

Such a design allows for a reduction in the dimensions of the system and the total number of components in it, and, as a result, significantly simplifies installation: there is no need to look for a place to install a separate control unit and pull wires to it. On the other hand, the built-in control unit is usually only responsible for its own valve and does not allow additional ones to be connected. And to control the system, you have to get to the valve every time, which can be very inconvenient. So it makes sense to pay attention to this option mainly in three cases: either if you need to cover only one point, if compactness and the minimum number of components are crucial, or if there are difficulties with installing a remote control unit.
