Description & Features
CV4100 is a high performance, safety focused eccentric rotary plug control valve for applications demanding higher rangeability, precise control and higher flow capacity. The eccentric plug does not contact with the seat ring until it fully closed. Therefore, it provides long seal life and smooth controllability by low torque without seat wear. Suitable for heavy duty services such like solid particles, slurry or fiber containing fluid, .etc.
Compact, robust design.
Low weight easy mounting.
Self-aligning eccentrically rotating, plug does not rub seat ring, less wear, less friction, more precision.
Higher capacity, stable throttling, low dynamic torque.
Full area and reduced capacity in all sizes.
Hard faced or soft seat provides tighter shutoff, and easier maintenance.
