5210Eccentric Rotary Control Valve
5210Eccentric Rotary Control Valve
Brief Description

Pneumatic eccentric rotary control valve (also called camflex) with Masoneilan technology combined with our characteristics, combines the advantages of single seat valves, ball valves, butterfly valves, etc., has a simple structure, small size, light weight, rated flow coefficient ,wide adjustable range, wide temperature range, low leakage, good stability and other advantages. Since the rotary action of valve body and the stem, so suffered little friction when in contact with the valve seat to close the valve body and the valve body to produce a slight elastic deformation of the flexible arm in the implementation structure and the elastic thrust during operation Tension force closer contact with the valve seat firmly, so eccentric valve leak is very small. While closing the valve, the required thrust of actuator is smaller than ball valves and butterfly. Therefore, the products are widely used in chemical, metallurgical, power plants and other industrial process control systems.

Details

1, The packing are similar as ball valve, which the sealing performance is much better than sliding stem valve, and the medium will be easy sealed by packing.

 

2, Simple flow channel, small flow resistance and double flow direction.

 

3, Wide range of temperature and whole casting of body and bonnet, which the temperature will be up to 450℃ if extended and finned bonnet are used.

 

4, Wide adjustable range, which can be 100:1

 

5,Small torque of open and close and small wear of plug and seat due to eccentric structure plug.

 

6, The big rate flow coefficient.

 

7,The instant shearing between plug and seat can cut fibers in medium and be automatically cleared of solid particles on the seat, especially for high viscosity and contained particles medium.

 

8,Small in size, low weight and steady working performance.
