Design ET, EAT, and ETR Sliding-StemControl ValvesDesign ET DescriptionDesign ET, EAT, and ETR general-purpose controlvalves (figures 1 through 3) are used for throttling oron-off control of a wide variety of liquids and gases. Allthree valve designs have single ports, balanced valveplugs, and cage guiding. Metal-to-PTFE seating forstringent shutoff requirements is standard in all valvesexcept those with Cavitrol� III cages. Metal-to-metalseating for higher temperatures is standard for valveswith Cavitrol III cages and optional for all other valves.

The temperature limits of Design ET valves can beextended above 232�C (450�F) by using PEEK (Poly-EtherEtherKetone) anti-extrusion rings in combinationwith a spring-loaded PTFE seal. The PEEK anti-extru-sion rings expand to close off the clearance gap be-tween the plug and the cage where the PTFE sealmay extrude at high temperatures and pressures. Thetemperature limits are extended to 316�C (600�F) fornon-oxidizing service and to 260�C (500�F) for oxidiz-ing service.

The easy-e � Valve Family

Design ET, EAT, and ETR control valves are part ofthe versatile easy-e family of industrial control valvesfrom Fisher Controls. easy-e valves share the follow-ing characteristics:

� Multiple trim material choices

� Interchangeable, restricted-capacity trims andfull-sized trims to match variable process flow de-mands

� Different cage/plug styles that provide particularflow characteristics for highly-specialized applications.The standard cage comes in three different flow char-acteristics:

� quick-opening� linear� equal percentage

� Whisper Trim� I and Whisper Trim III cages (fig-ure 5) that attenuate aerodynamic noise in gaseousservice.

� To eliminate cavitation damage in a properly-sized valve, a standard-travel, Cavitrol III, one-stagecage (figure 7) and a long-travel, Cavitrol III, two-stagecage are available in the 1- through 8-inch Design ETcontrol valve.

� Optional constructions allow full compliance withNational Association of Corrosion Engineers (NACE)recommendations.

Valve Features� Compliance with the Clean Air Act —

ENVIRO-SEAL packing systems (figures 8 and 9) thatprovide a superior stem seal to prevent the loss ofvaluable or hazardous process fluid are available.These packing systems feature PTFE or graphitepacking with live-loading for reduced packing mainte-nance.

� PTFE Seating for Long-Lasting Shutoff Capa-bility —Controlled compression of standard seatconstruction protects PTFE disk between metal diskseat and disk retainer (figure 4). Only the edge of thePTFE disk is contacted by the flowstream during nor-mal operation. Excellent shutoff is maintained by abackup ring or spring-loading that forces the valve plugseal ring against the cage (figure 4).

1. Refer to the valve specifications in this bulletin for pressure/temperature limits of valve parts. Do not exceed the pressure/temperature rating of the valve. Do not exceed any applicable codeor standard limitation.2. The Environmental Protection Agency (EPA) has set a limit of 500 parts per million (ppm) for fugitive emissions from a valve in selected VOC (Volatile Organic Compound) services.3. In vacuum service, it is not necessary to reverse the ENVIRO-SEAL PTFE packing rings.

Features (Continued)� Stable Control —Rugged cage guiding stabilizes

the valve plug at all points in its travel to reduce vibra-tion, mechanical noise, and the need for hydraulicsnubbers.

� Cost-Effective Operation and MaintenanceEconomy —Increased wear resistance of hardenedstainless steel trim means longer-lasting service.When inspection or maintenance is necessary, thebody can stay in the pipeline during removal of trimparts. Balanced valve plug construction permits use ofsmaller, lower-cost actuators from Fisher Controls.The Design ETR valve also permits easy body interioraccess without having to remove the bonnet or actua-tor (figure 3). And, trim inventory costs are cut be-cause dimensional standardization permits use ofmost standard easy-e trim parts.

� Compliance with European Standards —Valvesare available with dimensions specified by EN/DINstandards. See figure 14.

� Sour Gas Service Capability —Optional specialtrim and bolting materials are available for applicationshandling sour fluids and gases. These constructionscomply with the recommendations of the NationalAssociation of Corrosion Engineers (NACE) MR0175.Because of the care exercised by Fisher Controls inprocurement and manufacturing, additional testingand documentation to assure compliance with theNACE standard is not required, in most cases.

ENVIRO-SEAL, HIGH-SEAL PackingSystemsThe ENVIRO-SEAL and HIGH-SEAL packing systemsfrom Fisher Controls offer exceptional sealing capabili-ties. These systems easily install in existing valves orcan be purchased with new valves. These systemshelp seal the process to conserve valuable processfluid and to protect the environment against the emis-sion of toxic or polluting fluids. The long-life and reli-ability of these systems also reduce maintenance costand downtime.

For applications requiring compliance with environ-mental protection regulations, Fisher Controls offersthe unique ENVIRO-SEAL packing system (figure 9)and, for toxic or lethal service, the ENVIRO-SEAL bel-lows seal system (figure 8). The patented emissioncontrol packing system keeps emission concentrationsbelow the EPA 500 ppm requirement.

For a superior stem seal in applications that are notenvironmentally-sensitive, Fisher Controls offers theHIGH-SEAL graphite packing system (figure 9). TheHIGH-SEAL packing system provides superior sealingat pressure/temperature ratings beyondENVIRO-SEAL limits.

ENVIRO-SEAL packing systems, available with PTFE,graphite, or duplex packing, and the HIGH-SEALgraphite packing system feature live-loading andunique packing-ring arrangements for long-term, con-sistent sealing performance.

NACE Standard MR0175 ComplianceStandard procurement procedures and manufacturingprocesses used by Fisher Controls assure that controlvalves with sour service trims comply with the chemi-cal and physical requirements of NACE standardMR0175. Incoming raw materials are selected for sourservice trims by specifications covering chemical com-position, forming, hardness, heat treatment, and finish.In addition, the subsequent machining, welding, andheat treatment of the materials being processed intofinished parts is strictly regulated by manufacturingstandards.

Because of strict start-to-finish manufacturing qualitymanagement, Fisher Controls offers a high degree ofconfidence that the parts and assemblies provided forsour service comply with MR0175. Additional testingand documentation to assure compliance withMR0175 is not necessary, in most cases. However, incases where documentation is required, the followingitems can be provided:

� hardness test data

� certificate of compliance to specification

� heat treatment documentation

� chemical and physical test data

The requirements of the NACE standard are very spe-cific and the application of the standard to control

valve materials is quite complex. Some general guide-lines, however, are always followed:

� All carbon steel valve bodies and bonnets areheat-treated to 22 HRC maximum and are post-weldheat-treated.

� Martensitic and cast precipitation hardening stain-less steel are not used.

� Control valve packing sets are jam style only.

� Valve stems are made from S20910 (Nitronic 50).

� Plating and coatings are used only over suitablebase metals and are not intended for corrosion protec-tion.

� No machining operations that cause work hard-ening of the materials are performed in the manufac-turing process.

� Primary trim materials are S31600 and alloy 6

� Flat sheet gaskets are graphite/S31600 (316SST), spiral wound gaskets are Inconel 600/graphite

� Bolting in NACE MR0175 (non-exposed bolting)material is provided as standard. Bolting in NACEMR0175 (exposed bolting) material is available as anoption. See table 16.
