Electric valve VA7010 (Tianjin Shield)

A, VA7010 series of fan-coil electric valve Product Overview: 1, the drive motor: hysteresis synchronous motor 2, driver operating voltage: 200VAC, 50Hz / 60Hz (there is AC24V, 110V available) 3, power consumption: ≤5.7VA 4 , valve pressure: 1.6MPa 5, allowing the pressure: ≤0.12MPa 6, Medium: cold water, hot water 7, for medium temperature: 2 ℃ -95 ℃ 8, Ambient temperature: 0 ℃ -60 ℃ 9, closing time: Open for about 10 seconds, off for about 5 seconds Second, VA7010 series of fan-coil electric valve structure features: 1, forged brass body, stainless steel rods and springs, small size, corrosion resistance 2, the spool structure optimization. , without reducing the Kv value, allowing the pressure large. 3, the drive and the body separate, fast disassembly. 4, the drive has for system debugging and maintenance make the role of the manual lever.

Before installation, cut off about power and must be installed by a professional technician. 2, the flow direction must be the same direction of the arrow on the valve body. 3, the valve must be located above the coil connected to the water dish to ensure the event of falling into the water receiving drip pan. 4, valve and drive must be installed in the vertical direction within ± 60 ℃, above it should be at least 30mm space for disassembly. And around pipes, equipment, buildings must maintain sufficient space for maintenance operations, and must be installed by maintenance personnel manhole can reach to the place. 5, two and two or more electric valve can not be parallel, if do need to use a relay to isolate the parallel 6, the valve is installed with the pipe before installing a drive through the pressure test. 7, if the drive has been mounted on the body, then the drive must not be biased in the installation process, otherwise it will damage the drive. 8, the drive can not be wrapped with insulation materials, or affect its heat. 9, the drive must not be less than 1.5mm2 conductors reliable grounding line should be consistent with other relevant standards electrician. 10, and check after installation is complete correct, debugging power, should be observed at least three complete cycles run drive actuators, make sure all parts properly so far. 11, after anhydrous debugging qualified, then pass the water test. System up and down the water pressure must be strictly controlled within 0.15MPa, to ensure the effectiveness of electric valve for flow switch. Five, VA7010 series fan coil electric valve repair and maintenance: 1. IMPORTANT WARNING: You must first cut off the power supply before installation, repair and maintenance to avoid equipment injury. 2. If the valve should be immediately isolated from the system leaks, and replace the entire valve assembly. 3, if the drive does not work, replace the drive assembly, if the drive is working but able to get bit, you should clean the drive within the fan-shaped gear tooth surface, then the oil. Sixth, note VA7010 series fan coil electric valve precautions: inner drive gear ratio for high precision small modulus gear structure, when opening the valve with manual lever, hard to soft, so that the stem slowly down excessive force Meng It will damage the reducer.
