| | | Features Caging guiding, a Copes-Vulcan standard, includes a seating angle of 30° on the plug and 32° in the cage seat. Seat contact width 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-276, Type 420 stainless steel with Rockwell C-43 to C-47 hardness, ASTM A-351 Type 316 stainless steel with optional hardfacing and 17-4PH.

| | | This material is highly resistant to erosion and has proven most suitable for the service. Tolerance controlled machining and well defined quality control measures ensure consistent conformance to Copes-Vulcan engineering specifications. Cascade Trim has been fully tested and has many years of proven and successful service. On one test, conducted in a test loop of a major utility, it was operating only .05" (1.3mm) off the seat, with 300-350°F (149-177°C) water and 4400 psi (30,320 kPa) differential, for over one year. Upon inspection, the seating surfaces were still undamaged and the trim was kept in service. Other manufacturers' designs utilizing the same Type 420 stainless steel were also sampled under the same conditions. Maximum service gained from the other designs ranged from a few days to three months. | | |
