General

The Eccentric rotary control valve consists of a straight-trough valve body with minimal flow resistance and an open yoke plug with a wing that rotates eccentrically. It is suitable for applications requiring a large flow capacity and wide range ability, and for the control of those slurry fluids susceptible to clogging. The actuator is pneumatic diaphragm type, also available piston and electric actuator.

The main features are as follows: 

  1. Good sealing performance.
  2. Large flow coefficient.
  3. High stability of two kinds of dynamic.
  4. Wide application temperature.
  5. Compact, light weight, easy for installation.
  6. Valve body flow is simple, suitable for high viscosity and granular medium.
