Zhumadian electric valve, Zhoukou fan coil electric valve, Yongjia Inco electric valve manufacturer VA7010 series fan coil electric valve is suitable for on-off control of fan coil water flow. The valve body is forged in brass, and the drive is powered by a hysteresis synchronous motor. The valve is opened when the power is turned on, and the spring is reset after the power is turned off (that is, the valve body is closed automatically after the power is turned off). And equipped with a manual valve opening mechanism. It is one of the most commonly used electric valves for central air-conditioning systems.

Fourth, VA7010 series fan coil electric valve installation and commissioning:
1. Please read this manual carefully before installation, cut off the relevant power and must be installed by professional technicians.
2. The direction of water flow must be the same as the direction of the arrow on the valve body.
3. The valve body must be located above the coiled water receiving pan to ensure that it will fall into the water receiving pan when water drips.
4. The valve body and actuator must be installed within the vertical range of ± 60 ° C, and there must be at least 30mm space above it for disassembly. Sufficient maintenance operation space must be maintained with surrounding pipelines, equipment, and buildings. At the same time, it must be installed where the maintenance personnel can reach through the manhole.
5. Two or more electric valves cannot be connected in parallel. If they are required to be connected in parallel, they should be isolated by relays.
6. Install the driver after the valve body is installed and passed the pressure test with the pipeline.
7. If the driver is already installed on the valve body, you must not apply force to the driver during the installation and debugging process, otherwise the driver will be damaged.
8. The driver cannot be wrapped with thermal insulation material, otherwise it will affect its heat dissipation.
9. The driver must be reliably grounded through a wire of not less than 1.5mm2, and other lines should meet the relevant electrician standards.
10. After the installation is completed and checked for correctness, power on and debug. At least three complete operating cycles of the driver should be observed to ensure that all components are correct.
11. After passing the test without water, pass the water test. The pressure difference between the upper and lower water of the system must be strictly controlled within 0.15MPa to ensure the effectiveness of the electric valve to the water flow switch.

Five, VA7010 series fan coil electric valve repair and maintenance:
1. Important warning: The power must be cut off before installation, repair and maintenance to avoid causing equipment and personal injury.
2. If the valve is leaking, immediately isolate it from the system and replace the entire valve body assembly.
3. If the driver is not working, replace the driver assembly. If the driver is working but not in place, clean the tooth surface of the fan gear in the driver, and then lubricate.

Six, note VA7010 series fan coil electric valve Italy matters:
The reducer in the driver has a precision gear structure with a large speed ratio. When opening the valve with a manual operation lever, use gentle force to slow down the valve stem. Excessive force will damage the reducer.
