Fisher Large ED/EWD and ET/EWT Valves NPS 12 through 30

1 Large ED/EWD and ET/EWT ValvesNPS 12 through 30 Fisher NPS 12 through 30 CL150 through CL600ED/EWD and ET/EWT series control Valves are used foreither throttling or on-off control of a wide variety ofliquids and series Valves utilize a hanging cage and a seatring that is bolted into the valve body. These valveshave two graphite piston rings between the cage andplug, which provide up to a Class IV standard are used for high temperature applicationsbetween 316_C (600_F) and 593_C (1100_F). Shutoffcan be improved to Class V by using the Bore series Valves utilize a hanging cage and a seatring that is threaded into the cage . These Valves havetwo spring loaded seal rings, one between the cageand plug and another between the seat ring and valvebody, which provide up to a Class V standard are used for low to medium temperatureapplications between -46_C (-50_F) and 232_C(450_F). This temperature range can be extended to316_C (600_F) for non oxidizing service and to 260_C(500_F) for oxidizing service by using the HighTemperature (HTS1) temperature range of the ET/EWT series can beextended to cryogenic temperatures as low as -198_C(-325_F) with the ET-C and EWT-C specialized versionsof these Valves .

2 The specialized Valves feature uniquetrim, seals, and a longer extension bonnet to toleratethe extreme range of severe service trims are available for noiseabatement or cavitation control. Noise abatementtrims help with aerodynamic noise attenuation in gasservices and feature a Whisper trim III orWhisperFlo cage . Cavitation control trims helpprevent the damaging effects of liquid cavitation andinclude either a Cavitrol III cage (for services withoutentrained particulate) or Dirty Service trim (DST) set(for services with entrained particulate).W9156-1 Fisher NPS 24x20 Valve Assembly with Piston ActuatorFeaturesn Stable Control at High Pressure Drops Ruggedcage guiding stabilizes the valve plug at all points inits travel range.

Thisseal is available for all sizes and trims of the ET andEWT and allows the valve to be used in temperaturesup to 316_C (600_F) for non-oxidizing service and upto 260_C (500_F) for oxidizing service.

8 See tables 4and 6 for temperature limits and figure High Temperature Seal is used in place of thestandard plug seal ring and seat ring seal ring. This sealemploys a similar seal ring as the standard ET and EWT,but with the addition of an anti-extrusion ring, backupring, and retaining Service ET-C andEWT-CThe ET-C and EWT-C are designed to provide throttlingor on off control of liquids and gases at cryogenictemperatures as low as 198_C ( 325_F). These valvesare identical to the standard ET and EWT, but with afew differences, which allow the valve to tolerate thevery low temperatures. See tables 4 and 7 fortemperature limits and figure 5. These differencesinclude:n Style 3 Extension Bonnetn Bolted In Seat Ringn Cryogenic Plug SealThe style 3 extension bonnet is different from the style1 in that it is designed to locate the temperaturesensitive packing parts further away from the valvebody, preventing them from being exposed totemperature extremes.

9 The bolted in seat ring issimilar to that used with the ED or EWD valve andaccommodates the unavoidable material shrinkagethat occurs at cryogenic temperatures, which wouldotherwise loosen the ET or EWT s standard threaded inseat ring. The cryogenic plug seal is used in place ofthe standard ET or EWT plug seal ring. The maximumvalve shutoff that can be attained at these cryogenictemperatures with the cryogenic seal is Class SealThe Bore Seal is available for the ED and EWD only andis required for Class V shutoff applications where theservice temperature exceeds 316_C (600_F). Forservice temperatures below 316_C (600_F) the ET orEWT should be used when Class V shutoff is tables 4, 7, and 8 for temperature limits and figure Bore Seal employs a metal C shaped seal ring thatis secured to the outside diameter of the valve the valve plug comes into contact with the seatring, to close the valve, the Bore Seal is compressedagainst the cage wall thereby blocking a secondaryleakage path that exists between the plug and cagewall.

10 When the valve plug is not in contact with theseat ring ( valve open) the Bore Seal is not engagedand the piston rings that are also secured to theoutside diameter of the plug assume the role ofblocking this secondary leakage ET and ED ValvesD103554X012 Product :ET/ED ( Large )August 2017 11 Table 4.
