Principle And Installation Of Electric Actuator Two-Way Valve:
1. The Electric actuator two-way valve is used to control the opening and closing of cold or hot water air-conditioning system pipeline to control the room temperature.
2. Drive by single-phase hysteresis synchronous motor, Valve Spring Reset, valve is not working in a normally closed state, when need to work, by the Thermostat to provide an open signal, so that the electric two-way valve connected to the AC power and action.
3. Open the valve, the chilled or hot water enters the fan coil to supply air or heat to the room. When the room temperature reaches the set value of the thermostat, the thermostat turns off the power of the electric two-way valve and the reset spring closes the valve Thus cut off the water flow into the fan coil, through the valve closed and opened, so that the room temperature is always maintained in the temperature range set by the temperature control.
4. The drive and valve of the electric two-way valve are threaded to allow installation of the drive after the valve is installed. Field assembly, flexible and convenient wiring. The planar design of the driver can be installed close to the wall, take up little space, the product is reliable and durable, the working noise is low, and it can work reliably in the high temperature and high humidity environment in the hidden fan coil unit.
Installation And Commissioning Of 2 Way Electric Actuator Valve:
Before installation, read the instruction manual carefully, cut off the power supply and install it by professional and technical personnel.
The flow direction must be the same as the Arrow on the valve body.
The valve body shall be located above the coil pan to ensure that dripping occurs when falling into the pan.
The valve body and actuator shall be installed in a vertical direction within 60 °c with at least 30 MM space above it for assembly and disassembly. And the surrounding pipes, equipment, buildings must maintain adequate maintenance operating space, must be installed in the maintenance personnel through the manhole can reach the place.
After the valve body has been installed and the pipeline has passed the pressure test, the driver can be installed.
If the drive has been installed on the valve body, then in the installation and debugging process must not apply force to the drive, otherwise it will damage the drive.
After the installation is finished and the correctness is checked, the electricity is connected and debugged. At least three full cycles of the drive should be observed to ensure that all components are correct.
After the waterless debugging is qualified, then carry out the water test. The pressure difference must be strictly controlled within 0.15 MPA to ensure the effectiveness of the valve.
Application Of 2 Way Motorized Ball Valve:
Air Conditioning, heating, ventilation, domestic hot water and another civil system-level chemical, petroleum metallurgy, light power industry and other industries in the production process of automatic control.
