Please contact your Emerson ProcessManagement sales office for more details. Thesevalves have single ports, balanced valve plugs, andcage guiding.EUT-2andEWT-2valveswithahangingcage(figure3)are available for demanding applications in oil andnatural gas to 232_C(450_F). The hanging cage, withthe seat ring threaded into the cage, gives these valveseasy-maintenance trim--no trim parts are threadedinto the valve body. The seal between the plug andcage and the seal between the seat ring and valve bodyare spring-loaded PTFE seals.EUD and EWD valves (figure 4) have a bolted-in seatring. These valves have metal-to-metal seating and usetwo graphite piston rings between the valve plug andcage. They are used primarily for high temperature(over 232_C[450_F]) service. The Bore Seal is used toobtain Class V shutoff above 316_C (600_F).EUT and EWT valves (figure 1) have a bolted-in seatring. These valves have metal-to-metal seating and usePEEK anti-extrusion rings to obtain temperatures up to316_C(600_F).Thesevalvessharethefollowingcharacteristics:multiple trim material choices, trim partinterchangeability, and different cage styles to provideparticular flow characteristics to handle specificapplications.W9156-2To help reduce aerodynamic noise in gas service,Whisper TrimtIII (figure 5) and WhisperFlotcagesare available. To eliminate liquid cavitation damage,CavitroltIII cages are available. For cavitating liquidswith particulate, DST (dirty service trim) is available.EU ValveD102004X012Product Bulletin51.1:EUSeptember 2014
