Description
Pneumatic eccentric rotary control valve ( also call Flexure control valve) is developed by BCST based on Masoneilan technology. It has the advantage of a single-seated valve, ball valve, butterfly valve etc. And has the feature as below
- Simple structure
- Small Volume
- Lightweight
- Large rated flow coefficient
- Big adjustable range
- Wide using temperature
- Little leakage
- Good stable performance
As the disc and the stem only for rotary movement, so in the course of working, it suffered small friction, when the disc when seating in contact and closed, the spool around the arm will produce
small elastic deformation and elastic force tension under the thrust acting of the actuator to make the contact and closed, the spool around arm will produce small elastic deformation and elastic fore tension under the thrust acting of the actuator to make the contact between the disc and seat tighter, so the leakage of the eccentric valve is very small.
At the same time, the thrust acting of the actuator is small than the ball valve and butterfly valve when closing the valve. This series of products widely used in the chemical industry, metallurgy, power
plant s and another industrial process automatic control system
