Fisher? easy-e? ED easy-e ? ED, EAD, and EDR single-port control valves have balanced valve plugs, cage guiding, and metal-to-metal seating for all general applications over a wide range of process pressure drops and temperatures. These general purpose, sliding-stem valves are used for either throttling or on-off control of a wide variety of liquids and gases. Features and Benefits:

  • Optional constructions allow material compatibility with NACE MR0175/ISO 15156 and NACE MR0103. Contact your Emerson Process Management sales office for details.
  • 316 stainless steel packing box parts are standard (including packing flange, studs, and nuts)
  • Compliance with the Clean Air Act Optional 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.
  • Valve Plug Stability Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise.
  • More Flow Capacity for Initial Investment Streamlined flow passages in the the ED, EAD, and EDR valves provide excellent capacities and flow.
  • Balanced Valve Plug Construction Balanced valve plug construction permits use of smaller, lower-cost Fisher actuators. Also, trim inventory costs are cut because dimensional standardization permits use of most standard easy-e trim parts.
  • High-Temperature Capability with Class IV or Class V Shutoff Use of multiple graphite piston rings permit Class IV shutoff up to 593C (1100F).Use of C-seal trim permits Class V shutoff up to 593C (1100F).
  • Compliance with European Standards Valves are available with dimensions specified by EN/DIN standards.
  • Sour Service Capability Materials are available for applications handling sour service.
  • Operating Economy Increased wear resistance provided by standard hardened stainless steel trim means long service life.
  • Maintenance Economy The valve body can stay in the pipeline during removal of trim parts. The EDR valve also features easy valve access without removing the actuator.
