Fisher ET, EAT, and ETR Sliding-Stem Control Valves

Transcription

1 ET Valve D Product Bulletin Fisher ET, EAT, and ETR Sliding-Stem Control Valves Fisher ET, EAT, and ETR general-purpose control valves (figures,, and ) are used for throttling or on-off control of a wide variety of liquids and gases. All three valve designs have single ports, balanced valve plugs, and cage guiding. Metal-to-PTFE seating for stringent shutoff requirements is standard in all valves except those with Cavitrol III cages. Metal-to-metal seating for higher temperatures is standard for valves with Cavitrol III cages and optional for all other valves. The temperature limits of ET valves can be extended above C (5 F) by using PEEK (PolyEtherEtherKetone) anti-extrusion rings in combination with a spring-loaded PTFE seal. The PEEK anti-extrusion rings expand to close off the clearance gap between the plug and the cage where the PTFE seal may extrude at high temperatures and pressures. The temperature limits are extended to C ( F) for non-oxidizing service and to C (5 F) for oxidizing service. The ET product line is available for a wide range of applications, including sulfide and chloride stress-cracking environments common to the oil and gas production industries. To discuss available constructions, contact your Emerson Process Management sales office and include the applicable codes and standards required for these environments. The easy-e Valve Family ET, EAT, and ETR control valves are part of the versatile easy-e family of Fisher industrial control valves. easy-e valves share the following characteristics: Multiple trim material choices Interchangeable, restricted-capacity trims and full-sized trims to match variable process flow demands W9- FISHER ET CONTROL VALVE WITH 7 ACTUATOR Different cage/plug styles that provide particular flow characteristics for highly-specialized applications. The standard cage comes in three different flow characteristics: quick-opening, linear, or equal percentage. Whisper Trim I, Whisper Trim III (figure ), and WhisperFlo cages (figures and 5) attenuate aerodynamic noise in gaseous service. To help eliminate cavitation damage in a properly-sized valve, a standard-travel, Cavitrol III, one-stage cage (figure 8) and a long-travel, Cavitrol III, two-stage cage are available in the NPS through NPS 8 ET control valve.

2 Product Bulletin Features Compliance with the Clean Air Act ENVIRO-SEAL packing systems (figures 9 and ) that provide an improved stem seal to help prevent the loss of process fluid are available. These packing systems feature PTFE or Graphite ULF packing with live-loading for reduced packing maintenance. PTFE Seating for Long-Lasting Shutoff Capability Controlled compression of standard seat construction protects PTFE disk between metal disk seat and disk retainer (figure ). Only the edge of the PTFE disk is contacted by the flowstream during normal operation. Excellent shutoff is maintained by a backup ring or spring-loading that forces the valve plug seal ring against the cage (figure ). Valve Plug Stability Rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise. ET Valve D Cost-Effective Operation and Maintenance Economy Increased wear resistance of hardened stainless steel trim means longer-lasting service. When inspection or maintenance is necessary, the body can stay in the pipeline during removal of trim parts. Balanced valve plug construction permits use of smaller, lower-cost Fisher actuators. The ETR valve also permits easy body interior access without having to remove the bonnet or actuator (figure ). And, trim inventory costs are cut because dimensional standardization permits use of most standard easy-e trim parts. Compliance with European Standards Valves are available with dimensions specified by EN/DIN standards. See figure. Sour Service Capability Unless otherwise noted, references are to NACE MR75-. Optional materials are available to meet NACE MR and NACE MR75 / ISO 55. Material requirements under these standards vary by edition and year of issue; the specific standard must be specified.

6 Product Bulletin ET Valve D ENVIRO-SEAL, HIGH-SEAL Packing Systems ENVIRO-SEAL and HIGH-SEAL packing systems offer exceptional sealing capabilities. These systems easily install in existing valves or can be purchased with new valves. These systems help seal the process to conserve valuable process fluid. The long-life and reliability of these systems also reduce maintenance costs and downtime. For applications requiring compliance with environmental protection regulations, the unique ENVIRO-SEAL packing system (figure ) and a unique ENVIRO-SEAL bellows seal system (figure 9) are offered. The emission control packing system keeps emission concentrations below the EPA ppm requirement. For an excellent stem seal in applications that are not environmentally-sensitive, the HIGH-SEAL Graphite ULF packing system (figure ) is offered. The HIGH-SEAL packing system provides improved sealing at pressure/temperature ratings beyond ENVIRO-SEAL limits. ENVIRO-SEAL packing systems, available with PTFE, Graphite ULF, or duplex packing, and the HIGH-SEAL Graphite ULF packing system feature live-loading and unique packing-ring arrangements for long-term, consistent sealing performance.
