Cv/Kv Factors

Cage guiding, a Copes-Vulcan standard,includes a seating angle of 30°on the plug and 32°in the cage seat. Seat contactwidth is approximately .025" (.635mm). The valve actuator is selected to produce exceptionally tight seating under actual operating conditions. The high force produces a slight deformation of the seating surfaces, ensuring tight shutoff. The cage and plug are made of ASTM A-479, Type 410 stainless steel with Rockwell C-34 to C-38 hardness. This material is highly resistant to erosion and has proven most suitable for the service. Tape-controlled machining and well defined quality control measures ensure consistent conformance to Copes-Vulcan engineering specifications.
