Compliance with the Clean Air Act—Patented 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.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 and by up to 30 dbA with a Whisper Trim III 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.
