12- through 24 x 20- Inch Design EU & EW Valves The 12- through 24 20-inch Class 150 through 600 Designs EUT-2, EWT-2, EUD, and EWD general-purpose valves (figures 1, 2, and 3) are used for either throttling or on-off control of a wide variety of liquids and gasses. These designs have single ports, balanced valve plugs, and cage guiding. The Design EUT-2 and EWT-2 valves with a hanging cage (figure 2) are available for demanding applications in oil and natural gas to 450_F (232_C). The hanging cage, with the seat ring threaded into the cage, gives these valves easy-maintenance trim—no trim parts are threaded into the valve body. The seal between the plug and cage and the seal between the seat ring and valve body are spring-loaded PTFE seals. These valves are available with optional PTFE seating. The Design EUD and EWD valves (figure 3) have a bolted-in seat ring. These valves have metal-to-metal seating and use a graphite piston ring seal between the valve plug and cage. They are used primarily for high temperature (over 450_F [232_C]) service. These valves share the following characteristics: multiple trim material choices, trim part interchangeability, and different cage styles to provide particular flow characteristics to handle specific applications. To help reduce aerodynamic noise in gas service, Whisper TrimR III cages (figure 4) are available. To eliminate liquid cavitation damage, CavitrolR III cages are available. W6119/IL

D Stable Control at High Pressure Drops— Rugged cage guiding stabilizes the valve plug at all points in its travel range. This guiding reduces vibration, mechanical noise, and the need for hydraulic snubbers.

1. The pressure/temperature limits in this bulletin and any applicable standard or code limitation for valve should not be exceeded.
Economy—Streamlined flow passages provide greater capacities per initial investment than most globe valves of the same size. Balanced valve plug design can allow use of smaller actuators for high pressure drops.
2
Cost-Effective Operation—Increased wear resistance of the standard hardened stainless steel trim means longer-lasting service. Easy Maintenance—The valve can stay in the pipeline during removal of trim parts for inspection or maintenance.
