FISHER™ EWS 667 1049879

FISHER™ 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 4 x 2 through 12 x 8. 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. The FISHER™ EW product line is available for a wide range of applications, including sulfide and chloride stress cracking environments common to the oil and gas production industries. To discuss available constructions, contact your EMERSON™ sales office and include the applicable codes and standards required for these environments.

FISHER™ Plug Valve, Series: EWS Series, PTFE Softgoods

• 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, 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
• Increased pressure/temperature ratings - NPS 12 x 8 CL900 EW Series valve bodies with butt welding 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
