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 12×8 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 4×2 to 12×8 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.
