Fisher® easy-e™ EW
EW Series easy-e™ valves feature large internal cavities with expanded end connections and a variety of unbalanced and balanced plug designs. Sizes available from NPS 4x2 through 12x8. These combinations provide good fluid control in economical, high-capacity valve bodies that keep valve outlet velocities within practical limits. These valves meet a variety of service requirements, such as power plants where oversized piping is used to limit fluid flow velocity. They also perform well in noise abatement applications; for example, high-pressure gas reducing stations where sonic velocities are often encountered at the outlet of conventional valve bodies.

Compliance with the Clean Air Act– ENVIRO-SEAL™ packing systems provide an improved stem seal to help prevent the loss of valuable or hazardous process fluid. The ENVIRO-SEAL packing systems feature PTFE or Graphite ULF packing with live-loading for reduced packing maintenance.
Noise Attenuation–In an EW Series valve, noise produced by high flow rates and large pressure drops can be reduced by up to 18 dbA with a Whisper Trim I cage, by up to 30 dbA with a Whisper Trim III cage, and by up to 40 dbA with a WhisperFlo cage.
Piping Economy–Expanded end connections of EW Series valve bodies may reduce the need for line swages while accommodating oversized piping arrangements used to limit fluid flow velocities.
Temperature Compensation–On designs with the seat ring threaded into the valve body (figure 4), the hung cage feature helps reduce gasketing problems caused by thermal expansion and contraction of long parts, such as the cage assembly.
Standard Trim Parts across the easy-e product line–Included are FGM gaskets, packing flange, studs, and nuts.
High-Temperature, Class IV or Class V Shutoff–Optional multiple piston rings (figure 14) for EWD and EWD-1 valve bodies permit Class IV shutoff up to 593_C (1100_F). Use of C-seal trim for EWD (see figure 5) permits Class V shutoff up to 593_C (1100_F).
Increased Pressure/Temperature Ratings–NPS 12x8 CL900 EW Series valve bodies with buttwelding end connections are capable of increased ASME ratings called Intermediate Standard Ratings. The extra strength of the valve body allows these valves to be used where pressures and temperatures exceed Standard Class ratings in ASME B16.34. See Bulletin 59.1:027, Increased Pressure/ Temperature Ratings for EH and EW Series Steel Valves (D100076X012), for further information.
Sour Service Capability– Unless otherwise noted, references are to NACE MR0175-2002. Optional materials are available to meet NACE MR0103 and NACE MR0175 / ISO 15156. Material requirements under these standards vary by edition and year of issue; the specific standard must be specified.
