Summary
ZLSM Series fan-coil electric valve is applied to on-off control for fan-coil water system. In need of work, the temperature controller will provide an open signal, enable the electric valve connect to the AC power, then start the valve, cool water or hot water enter into fan-coil, provide cool or warm air to the room; when the room temperature reaches to setting value, the temperature controller will cut off the electric valve, and the restoring spring will close the valve, so as to prevent the water enter into fan coil. Through the valve¡¯s open and close, keep the room temperature within setting range. This series electric valve could match with various temperature controllers, as to realize energy saving operation for air condition system. K type driver has built-in auxiliary switch, could control other equipments synchronously. |

Notice on installation:
¡ô Normally closed two-way valve and split three-way valve shall be installed according to figure 1, 2 and 3. The compression release valve shall be applied to the bottom branch pipe for tall building.
¡ô The motor housing should prevent drop permeate. When install the valve, the driver shall not be installed under pipe.
¡ô When the valve is installed in the vertical pipe, the motor shell must prevent drops permeate.
¡ô Manual lever: when move the lever to the arrow direction slowly and press the loophole, the valve is on open status. When the current electrifies the electric valve, the manual lever will be reset to automatic position.
¡ô Install the electric valve horizontally; the motor should be above the valve body.
¡ô Water flow direction shall be same as arrow in the valve body.
¡ô Note: the driver shall not be the force pivot while installing. |
