Electric valve

Electric valve

— valves, predominantly of ball type, used in heating systems and domestic hot water circuits to control the flow of water. When an electrical signal is applied to the drive of the motor connected to the valve, the valve is opened or closed. In the event of a power failure, it is usually possible to manually open or close the valve. There are two-, three- and four-way valves with electric drive. They are suitable for controlling the flow of the heat medium, remote control of the flows in two-circuit systems, remote mixing, and opening or shutting off water flow from several circuits, respectively. Electric valves can be used in conjunction with a flood sensor to automatically shut off the water supply when leaks are detected in the circuit.
