VA-7010 Brass Electric Three-way Valve Overview
VA-7010 Brass Electric Three-way Valve produced and sold by Baigang valve group for fan coil water flow control. Body forged brass, the drive using hysteresis synchronous motor as the driving force. Power open the valve, reset by the spring after the power is off (that is, the body off after power off), and with a manual valve operating mechanism is the central air conditioning system is one of the most widely used electric valve.

VA-7010 Brass Electric Three-way Valve installation and commissioning
◆ Before installation must read the instructions, cut off the power and must be installed by professionals. 
◆ The flow direction must be the same as the direction of the arrow on the valve body. 
◆ The valve body must be above the fan water tray to ensure that dripping water will fall into the water receiving tray. 
◆ The valve body and driver must be installed within ± 60 ° in the vertical direction. At least 30mm above the space should be used for disassembly and assembly. The surrounding piping, equipment and buildings must maintain sufficient space for maintenance and repair, and must be installed in the maintenance personnel Through the access hole can reach places. 
◆ two and more than two electric valve can not be parallel, if you really need to use relays parallel isolation. 
◆ After installing the valve body and passing the pressure test to the pipeline, install the drive. 
◆ If the driver has been installed on the valve body, the driver must not be used during installation and commissioning as this may damage the driver. 
◆ The drive can not be wrapped with insulation material, otherwise it will affect its heat dissipation. 
◆ The driver must be reliably grounded through a wire of not less than 1.5mm2. The other wires should comply with the relevant standards of the electrician. 
◆ Installation is complete and check the correct, water-free power debugging. At least observe the three full drive cycles and make sure all components are correct and correct. 
◆ after passing through the anhydrous test, and then through the water debugging. System pressure on the water must be strictly controlled within 0.13MPa, in order to ensure the effectiveness of the electric valve on the water flow switch.
