1. This is a special non-ANSI/FCI leakage class.
2. Class V shutoff requires spring-loaded seal ring, radiused-seat plug, and wide-bevel seat ring (not available with 8-inch port, quick-opening cage). Not available with trims 4, 29, and 85.
Description
These single-port valves have cage guiding, quick-change trim, and balanced push-down-to-close valve plug action.
Valve configurations are as follows:
ET--Globe-style valve (figure 1) with metal-to-PTFE seating (standard for all except Cavitrol III cages) for stringent
shutoff requirements, or metal-to-metal seating (standard for Cavitrol III cages, optional for all others) for higher
temperatures.
