Fisher™ EW Series (EWD/EWS/EWT) Sliding-Stem Control Valves through NPS 12x8 The Fisher easy-e EW series product line is available for a wide range of applications common to the oil and gas production industries. 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. Features ENVIRO-SEAL™ packing systems provide an improved stem seal to help prevent the loss of process fluid. The ENVIRO-SEAL packing systems feature PTFE, Graphite ULF, or Duplex packing with live loading for reduced packing maintenance. 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. NPS 12x8 CL900 EW series valve bodies with buttwelding end connections are capable of increased ASME ratings, called Intermediate Standard Ratings. Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise. Streamlined flow passages provide excellent capacities and flow. NPS 4x2 to 12x8 valves are available with dimensions specified by EN/DIN standards. Materials are available to meet NACE standards. Increased wear resistance provided by standard, hardened stainless steel trim means long service life.
