Electric three-way valve 返回列表页

Features:

1. actuators use cast aluminum frame and plastic shell, small size and light weight.
2. use of permanent magnet synchronous motor, with a hysteresis clutch body, a reliable self-protection.
3. for a variety of control signals: incremental （floating point）, voltage （0 ~ 10V）,current （4 ~ 20mA）.
4. a 0 ~ 10V or 4 ~ 20mA feedback signal （optional）.
5. gear metal gear, greatly improving the life of the drive.
6. low power consumption, output force, noise.
7. body with bronze, cast iron, ductile iron, a variety of materials available to suitdifferent working fluid and temperature requirements.
8. valve body with threaded connections and flanges connecting the two, easy to install.
9. body structure are: links confluence valve, three shunt valve.


How it works:

  This system is suitable for a new air unit air conditioning system in summer and winter temperature control. As shown below, the temperature sensor TE-1, PItemperature controller TC-1 and the electric control valve TV-1 supply air temperature control system components, air supply pipes installed in the TE-1, the temperature signal detected Sent to the TC-1, the TC-1 to TE-1 and set the value of the detectionvalue of the constant comparison, while continuing to output signals to control the TVthe opening of a connection 1 adjustable, and finally to TE-1 temperaturemeasurement Maintain the set temperature range.
     DPS-1 air-pressure switch is used to detect the permeability of the filter case, filterthe dirty, the ventilation rate is lower, the greater the pressure difference on both sides. When the pressure difference exceeds the set value of the DPS-1, the micro switch operation, an alarm signal.
      When the coil temperature is lower than after a certain limit, the low-temperatureprotection switch TS-1 cut off the power supply fan, which
The new air valve closed, to prevent freezing of water within the coil, coil split up.
      SW-1 is built-in cold / warm running conversion.
