CV20

Image: 

The CV20 control valve is a rugged, compact, freezeless dump valve. The angle body can be installed so that the valve cage and plug are submerged into the process media giving the valve its freezeless characteristic. Typical installations include separators, scrubbers and other production vessels.

  • The hammer union makes maintenance easy by allowing the topworks to be removed without taking the valve out of line.
  • Offers the versatility of multiple trim sizes and material options in addition to the same trim set as the CV10.
  • A NACE option is available for sour service.
