ZDR-35212 ZDR-35222 Electric eccentric rotary valve

Overview

The ZDR-35212 ZDR-35222 Electric eccentric rotary valve is different from the usual column base valve, butterfly valve, ball valve, etc. It is equipped with a spherical core in a straight-through valve body. The center of the spherical valve core deviates from the center of the spool shaft. When the shaft rotates, it is installed in The spherical movement on the rotating shaft makes cam-like eccentric rotation with respect to the center of the microbody, and relies on the elastic deformation of the flexible arm of the valve core to make the spherical surface of the valve core closely contact the sealing surface of the valve seat to achieve a reliable seal.

Feature

ZDR-35212 ZDR-35222 Electric eccentric rotary valve

1. No need to equip additional servo amplifier, it can work after connecting signal and power.  

2. It has an indication of charge loss and signal interruption.

3. It is convenient to choose the valve position self-locking, fully open or fully closed when the power is off.

4. It can easily realize the conversion of electric on and off working mode.

5. It can easily choose the input signal 4~20mAd.c or 1~5Vdc.

6. Good sealing.

7. A larger rated flow coefficient can be obtained.

8. The use temperature range is wide.

9. The valve body has a simple flow path, which is suitable for high-viscosity and particle-containing media. The whole machine is small in size, light in weight and good in working stability.
