Description

ET Series Pneumatic globe type control valves are used in steam conditions, also can throttling or on-off control of a wide variety of liquids and gases. ET series designs include single ports, balanced valve plugs, and cage guiding. Metal to PTFE seating for stringent shutoff requirements is standard in all valves, and metal to metal seating for high temperature is standard for valves with Cavitroll cages.

Performance:

  • Multiple trim material options
  • Interchangeable, restricted capacity trims, and full-sized trims to match variable process flow needs.
  • Different cage/plug styles provide particular flow characteristics for highly specialized applications. The standard cage comes in three different flow characteristics: quick-opening, linear, or equal percentage.
  • To help eliminate cavitation damage in a properly-sized valve, a standard-travel, Cavitrol III,
    one-stage cage (figure 9) and a long-travel, CavitrolIII, two-stage cage are available in the NPS 1 through NPS 8 ET control valve.

Technical characteristics:

  • Sizes: 1/2”, 3/4”, 1”, 1-1/2”, 1-3/4”, 2″, 3″, 4″, 5”,  6″, 8″
  • Ratings: up to ANSI 150, 300, 600
  • Connection: Flanged, butt-welded, socket-welded, and threaded
  • Leakage Standard: ANSI/FC, IEC60534-4
  • Flow direction: flow to open, flow to close
  • Materials: A216 Cr. WCB, SS304, SS316, CF8M, CF3M, CF3, CF8, LCB, LCC, 2205, Duplex stainless steel etc.
