Application range and product characteristics of electric two-way valve
1. It is used to control the opening or closing of the pipes of the 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 valve connect to the AC power supply and act. 3. Open the valve, chilled water or hot water enters the fan coil unit to 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 valve, and the reset spring will close the valve, thereby Cut off the water flow into the fan coil unit, and close and open the valve to keep the room temperature within the temperature range set by the temperature control. 4. The driver of the ZYFT series electric valve is connected with the valve in a threaded connection, and the driver can be installed after the valve is installed. On-site 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 reliably in the high temperature and high humidity environment that often occurs in the concealed fan coil unit. The actuator adopts cast aluminum bracket and plastic shell, which is small in size and light in weight. It adopts permanent magnet synchronous motor and has a hysteresis clutch mechanism, which has a reliable self-protection function. It is suitable for various control signals: incremental (floating point), Voltage (0～10V), current (4～20mA) ★With 0～10V or 4～20mA feedback signal (optional) ★The transmission gear adopts metal gear, which greatly improves the service life of the driver ★Low power consumption and large output force , low noise ★The valve body is available in cast copper, cast iron, cast steel and stainless steel to suit the requirements of different working media and temperatures ★The valve body has two types of threaded connection and flange connection, which is easy to install and its structure In line with IEC international standards ★The valve body structure includes two-way valve (single seat), two-way balance valve (balanced), three-way confluence and three-way diverter valve. It is divided into two types: direct-acting and pilot-operated.
