Summary
    VA-7010 Series Fan-coil Electric valve is applied to on-off control for fan-coil water system. The valve body is casted with excellent brass and the driver is driven with hysteresis synchronous motor. Open the valve after electrifying, reset with spring after power off (the valve body closes automatically after power off), it matches with manual valve actuating mechanism, is one of most ordinary valve that applied to central air-conditioning system.
Technical data：
◆ Driving motor：hysteresis synchronous motor
◆ Driving voltage：220VAC, 50Hz/60Hz (AC24V, 110V are available for choice)
◆ Power consumption：≤7.5VA

◆ Open and close time：about 10 s for open，about 5 s for close

◆  Connection manner：ZG internal pipe thread （could be custom made）
◆ Distance of run (Theoretical value): 4.0mm
Main material:
◆  Valve body: brass (casting)
◆  Valve stem: 304 stainless steel
◆  Sealing material：special rubber
◆  Driver chassis: die-casting aluminum alloy
◆  Driver cover: flame retardant ABS engineering plastic
Installation and debugging:
◆  Please read this instruction carefully before installation, cut off power and ask professional for installation.
◆  Water flow direction shall be same with the direction of arrow in the valve body.
◆  The valve body shall be above fan defrosting tray, as to ensure the drops fall into tray.
◆ The valve body and driver shall be installed within ±60° of vertical direction, with at least 30mm space for dismounting, keep enough space for maintenance operation from round pipe, equipment and construction, but should be also installed to the place could be reached by maintenance personnel through manhole.
◆ Two and above two electric valves should not be parallel connected, use relay to insulate in need of parallel connection.
◆ Install the driver after finishing valve body installation and pipe testing
◆  If the driver is already installed in the valve body, never apply force on driver during the course of installation and debugging, or it may damage the driver.
◆  The driver shall not be packed with insulating material, or it may affect abstraction of heat.
◆ The driver shall be earthed with wire not less than 1.5 mm2, other circuit shall conform to relevant standard.
◆  Take water-free power debugging after completion of install and check. Observe at least three completed running periods, ensure all parts are normal and right.
◆ After passing water-free debugging, take water-supply debugging. The pressure difference of upper and lower water should be strictly controlled within 0.13Mpa, as to ensure efficient on water flow switch.
