Product Descriptions: VA7010 Series switch electric valve is composed ofVAA7010 series valve motor and VAV7010 series copper valve. Opening or closing the switch that controls the cold or hot water in the system pipes of the air conditioner controls the room temperature. The motor is generated by one-way synchronous machine of stagnant magnetism and the valve is spring reset. The valve is closed when it stops working. While it works, the temperature control will give out an open signal. Then the electric valve will put through the alternating current to open the valve. The cold or hot water will then flow into the fan coil to supply the cool or heat for the room. When the room temperature reaches the set temperature, the temperature control will let the electric valve cut off the power. And the return spring closes the valve to prevent the water from flowing into the fan coil. Opening or closing the valve always keeps the room temperature in the range set by the temperature control. The motor and the body of VA7010 series electric valve is connected by spiral joint. The motor is fixed after the valve installation. On-spot installation and flexible wiring is easy and convenient. The motor's plane can be fixed close to the wall so that less space is occupied. This is a durable product with reliable performance and low working noise. It can also work stably in the environment of high temperature caused by the hidden fan coil device.
