The electric ball valve is composed of a valve body and a driver. The utility model has the advantages of simple structure, reliable operation, strong fluid passing capacity, energy saving, etc. It can be widely used in the on-off control of heating, central air conditioning, solar hot water system and water treatment system.

 

 

 

Technical parameters:

 

 

 

Driving voltage: AC220V & lusmn; 10%, 50 / 60Hz

 

 

 

Power consumption: 5VA (only when the valve is opened and closed)

 

 

 

Action time: ≥ 15s

 

 

 

Nominal pressure: 1.6Mpa

 

 

 

Applicable medium: cold, hot water or low-pressure steam (≤ 0.4MPa)

 

 

 

Medium temperature: 1-90 ℃

 

 

 

Ambient temperature: 0-65 ℃

 

 

 

Connection mode: ZG internal pipe threaded fan coil electric ball valve has a built-in contact switch. After the valve is opened and closed, the motor is not powered, so it has a long life, energy saving and special safety. The valve body is separated from the driver and can be disassembled quickly. The valve body has unique structure, large flow, no slag plugging and large closing differential pressure. The actuator adopts eccentric structure, which can be installed after the equipment and pipeline are installed. It is easy to disassemble and install, which is conducive to improving the installation efficiency. The actuator can be adapted to 1 / 2 ", 3 / 4" and 1 "valve bodies. It is applied to the on-off of fan coil of central air conditioning, cold water / hot water of solar energy system and other fluid systems.

 

 

 

[structural features]

 

 

 

1. Body brass forging, stainless steel rod and spring, small volume, corrosion resistance

 

 

 

2. The valve core structure is optimized, and the allowable pressure difference is large without reducing Kv value.

 

 

 

3. The driver is separated from the valve body and can be disassembled quickly.

 

 

 

4. The driver has a manual operating lever which can be used for system debugging and maintenance.

 

 

 

Three wire two control, two live wires, one zero wire (one open valve wire plus one close valve wire plus common zero wire) control valve. The blue line is the valve closing line, the red line is the valve opening line, and the black line is the common line.

 

 

 

 

[installation and commissioning]

 

 

 

1. Read this manual carefully before installation, cut off the power supply and install it by professional technicians.

 

 

 

2. The flow direction must be the same as the arrow on the valve body.

 

 

 

3. The valve body must be located above the coil drain pan to ensure that water drops into the drain pan.

 

 

 

4. The valve body and driver must be installed in the vertical direction & lusmn; 60 ℃, and there should be at least 30mm space above it for disassembly and assembly. Sufficient maintenance and operation space must be maintained with surrounding pipelines, equipment and buildings, and must be installed at the place accessible to maintenance personnel through the manhole.

 

 

 

5. Two or more electric valves shall not be connected in parallel. If it is necessary to connect in parallel, the relay shall be used for isolation

 

 

 

6. The driver shall not be installed until the valve body has been installed and the pipeline has passed the pressure test.

 

 

 

7. If the driver has been installed on the valve body, the driver shall not be forced during installation and commissioning, otherwise the driver will be damaged.

 

 

 

8. The driver shall not be wrapped with thermal insulation material, otherwise its heat dissipation will be affected.

 

 

 

9. The driver must be reliably grounded through a conductor of not less than 1.5mm2, and other lines shall conform to relevant electrical standards.

 

 

 

10. After the installation is completed and checked to be correct, power on for debugging. Observe at least three complete operation cycles of the driving actuator until all components are correct.

 

 

 

11. After water free commissioning, water test shall be conducted. 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.

 

 

 

[repair and maintenance]

 

 

 

1. Important warning: before installation, repair and maintenance, the power must be cut off to avoid equipment and personal injury.

 

 

 

2. If the valve leaks, immediately isolate it from the system and replace the entire valve body assembly.

 

 

 

3. If the driver does not work, replace the driver assembly. If the driver is working but not in place, clean the internal sector gear tooth surface of the driver, and then lubricate it
