Product Description
Overview of VA-7010 electric two-way valve:
VA7010 electric two-way valve is designed for central air conditioning fan coil supporting products, by the driver and the valve body of two parts, the driver is driven by a synchronous motor, with spring reset and manual valve opening lever control function. The valve body part adopts the piston type structure. The electric two-way valve can be used in conjunction with the thermostat. The thermostat controls the electric two-way valve motor to open or close the valve to realize the on or off of cold water or hot water in the pipeline, and then send air through the fan coil to realize the temperature Automatic adjustment.
VA-7010 electric two-way valve product features:
1. It is used to control the opening or closing of the pipes of cold water or hot water air conditioning system to achieve the purpose of controlling the room temperature. 2. The driver is driven by a single-phase hysteresis synchronous motor, the valve spring is reset, and the valve is in a normally closed state when it is not working. When it needs to work, the thermostat provides an opening signal to make the electric two-way valve connect to the AC power supply and act. 3. Open the valve, provide air-conditioning or heating for the room. When the room temperature reaches the set value of the thermostat, the thermostat will power off the electric two-way valve, and the reset spring will close the valve, thereby cutting off the water flow into the fan coil. The valve will be closed and opened to keep the room temperature within the temperature range set by the temperature control. 4. The driver of VA7010 series electric two-way valve is connected with the valve by thread, and the driver can be installed after the valve is installed. Field assembly, flexible and convenient wiring. The plane design of the driver can be installed close to the wall, occupying a small space, the product is reliable and durable, the working noise is low, and it can work in the high temperature and high humidity environment in the concealed fan coil unit.
