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.
