    Product introduction
  The imported electric two-way valve produced by Blair can be driven by electric means, flanged or threaded by the connection method, two-way valves can be used by the structure, and soft seals can be used by the seal structure. The pressure range is PN150-300LB, and the nominal diameter is DN15-600mm, the material can choose cast iron, WCB, copper, stainless steel, etc. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
    Product Details
Imported electric two-way valve American Buhrer brand This system is suitable for winter and summer temperature control of new fan units of air conditioning systems. As shown in the figure below, the supply air temperature control system is composed of a temperature sensor TE-1, a proportional integral temperature controller TC-1 and an electric regulating valve TV-1. It is installed in the TE-1 of the supply air duct and sends the detected temperature signal. Send to TC-1, TC-1 will continuously compare the detection value of TE-1 with the set value, and at the same time continuously output signals to control the opening degree of TV-1 to adjust the connection, and finally make the ambient temperature measured by TE-1 Keep within the set temperature range.
    The air pressure differential switch DPS-1 is used to detect the air permeability of the filter. The dirtyer the filter, the lower the air permeability, and the larger the pressure difference between the two sides. When the pressure difference exceeds the set value of DPS-1, the micro switch operates and issues an alarm signal.
     When the temperature behind the coil is below a certain limit, the low temperature protection switch TS-1 cuts off the power of the blower, so that
Close the fresh air damper to prevent the water in the coil from freezing and causing the coil to burst.
     SW-1 is a built-in cold / warm running state conversion.

Product features of two-way valve:
1. The actuator adopts cast aluminum bracket and plastic shell, which is small in size and light in weight.
2. Use permanent magnet synchronous motor with hysteresis clutch mechanism, with reliable self-protection function.
3. Suitable for a variety of control signals: incremental (floating point), voltage (0 ~ 10V), current (4 ~ 20mA).
4. With 0 ~ 10V or 4 ~ 20mA feedback signal (optional).
5. The transmission gear adopts metal gear, which greatly improves the service life of the driver.
6. Low power consumption, high output power and low noise.
7. The valve body is available in various materials such as cast copper, cast iron and ductile iron to suit different working medium and temperature requirements.
8. The valve body has two types of screw connection and flange connection, which is easy to install.
9. The structure of the valve body includes: two-way valve (single seat), two-way balance valve (balanced).
