Description
The eccentric rotary valve is different from the usual plunger valve, butterfly valve, ball valve, etc. It installs a spherical valve 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 valve core on the rotating shaft rotates eccentrically in the shape of a cam relative to the center of the valve body, and relying on the elastic deformation of the flexible arm of the valve core, the spherical surface of the valve core is in close contact with the sealing surface of the valve seat to achieve a reliable seal.
The electric eccentric rotary control valve has the following characteristics:
1. No need to equip additional servo amplifier, just connect signal and power supply to work.
2. With power failure and signal failure instructions.
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 power-on and power-off working modes.
5. It is convenient to choose the input signal 4-20Ma.DC or 1-5V.DC.
6. Good airtightness.
7. A larger rated flow coefficient can be obtained.
8. Wide operating temperature range.
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.
