Comprehensive Guide to Electric Butterfly Valves: Principles, Applications, and Advantages
Electric butterfly valves play a crucial role in industrial automation, off...
HMG brass motorized ball valves are composed of two parts: the valve body and the driver. It has the advantages of simple structure, reliable work, strong fluid passing capacity and energy saving. It can be widely used for on-off control of cold and hot water in heating, central air-conditioning, solar water heating systems, and water treatment systems; it can also be used for on-off control of low-pressure steam. Varieties include two-position two-way and two-position three-way.

1. The SW is connected with the blue wire, and the valve is open: When it is in place, the
internal power will be automatically cut off, and the valve will remain in the open state.
2. The SW is connected to the brown wire, and the valve is closed: When it is in place, the
internal power will be automatically cut off, and the valve will remain in the closed state.

1. Normally closed control mode: when the brown wire is closed, the valve opens; when it
is in place, the internal power is automatically cut off, and the valve remains in the open state.
2. Normally closed control mode: when the brown wire is disconnected, the valve is closed;
when it is in place, the internal power is automatically cut off, and the valve remains in the closed state.
3. Normally open control mode: when the brown wire is closed, the valve is closed; when it
is in place, the internal power is automatically cut off, and the valve remains in the closed state.
4. Normally open control mode: when the brown wire is disconnected, the valve opens;
when it is in place, the internal power is automatically cut off, and the valve remains in theopen state.
Note: The power-on time is not less than 2 minutes (otherwise the backup power supply
cannot be triggered to close or open the valve)

| Three lines and one control Voltage: 220VAC/110V |
The second line is reversed Voltage: DC5V/12V/24V

1. When the live wire and the neutral wire have power, the blue wire is closed and the
valve is opened: the internal power is automatically cut off when it is in place, and the
valve remains in the open state.
2. When the live wire and the neutral wire have electricity, the blue wire is disconnected
and the valve is closed: when it is in place, the internal power is automatically cut off, and
the valve remains in the closed state.

1. SW is a double switch, SW is connected with the black wire, and the valve is open: when
it is in place, the internal power will be automatically cut off, and the valve will remain in
the open state.
2. The SW is connected to the brown wire, and the valve is closed: When it is in place, the
internal power will be automatically cut off, and the valve will remain in the closed state.
