Design ED, EAD, and EDRSliding-Stem Control ValvesDesign ED, EAD, and EDR single-port control valvesshown in figures 1 through 4 have balanced valveplugs, cage guiding, and metal-to-metal seating forall general applications over a wide range of processpressure drops and temperatures. These generalpurpose, sliding-stem valves are used for eitherthrottling or on-off control of a wide variety of liquidsand gases.

The easy-e� Valve Family

Design ED, EAD, and EDR valves are part of theversatile easy-e family of industrial control valvesfrom Fisher. easy-e valves share the followingcharacteristics:

� Multiple trim material choices

� Trim temperature capability with standard metalseats to 427�C (800�F)

� FGM gaskets

� Interchangeable, restricted-capacity trims andfull-size trims match variable process flow demands

� Different cage/plug styles provide particularflow characteristics for highly-specializedapplications. The standard cage comes in threedifferent flow characteristics:

� quick-opening� linear� equal percentage

� Noise in gaseous service may be attenuated byusing Whisper Trim� I, Whisper Trim III (figure 10),and WhisperFlo� cages (figure 12)

� Optional constructions provide full compliancewith National Association of Corrosion Engineers(NACE) recommendations. See page 16.

� 316 stainless steel packing box parts arestandard (including packing flange, studs, and nuts)

Features� Compliance with the Clean Air Act—Optional

ENVIRO-SEAL packing systems (figure 7) provide asuperior stem seal to prevent the loss of processfluid. The ENVIRO-SEAL packing systems featurePTFE, graphite, or duplex packing with live-loadingfor reduced packing maintenance.

� Stable Control at High Pressure Drops—Rugged cage guiding stabilizes the valve plug at allpoints during travel. Cage guiding reduces vibrationand mechanical noise.

� More Flow Capacity for Initial Investment—Streamlined flow passages provide greatercapacities. When compared to globe valves of thesame line size by other manufacturers, the DesignED, EAD, and EDR provide more flow.

� Balanced Valve Plug Construction—Balanced valve plug construction permits use ofsmaller, lower-cost actuators from Fisher. Also, triminventory costs are cut because dimensionalstandardization permits use of most standard easy-etrim parts.

� High-Temperature Capability with Class IVor Class V Shutoff—Use of multiple graphite pistonrings (figure 2) permit Class IV shutoff up to 593�C(1100�F).Use of C-seal trim (see figure 6) permits Class Vshutoff up to 593�C (1100�F).

� Compliance with European Standards—Valves are available with dimensions specified byEN/DIN standards. See figure 14.

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

� Operating Economy—Increased wearresistance provided by standard hardened stainlesssteel trim means longer service life.

� Maintenance Economy—The valve body canstay in the pipeline during removal of trim parts. TheDesign EDR valve also features easy valve accesswithout removing the actuator.

C-seal Trim DescriptionC-seal trim is available for valves with port diametersfrom 2-7/8 inches through 8 inches.

With C-seal trim, a balanced valve can achievehigh-temperature, Class V shutoff. Because theC-seal plug seal is formed from metal (N07718nickel alloy, Inconel 718) rather than an elastomer, avalve equipped with the C-seal trim can be applied inprocesses with a fluid temperature of up to 593�C(1100�F).

ENVIRO-SEAL and HIGH-SEALPacking Systems

ENVIRO-SEAL and HIGH-SEAL packing systemsoffer exceptional sealing capabilities. They easilyinstall in your existing valves or can be purchasedwith new valves. These systems may help preventthe loss of process fluid. The longer operational lifeand reliability of these systems also reduces yourmaintenance costs and downtime.

For applications requiring compliance withenvironmental protection regulations, Fisher offersthe unique ENVIRO-SEAL packing system (figure 7)and, for service where the customer desiresleak-free operations, Fisher offers a uniqueENVIRO-SEAL bellows seal system (figure 8). Thepatented emission control packing system keepsemission concentrations below the EPA 500 ppmrequirement.

For a superior stem seal in applications that are notenvironmentally-sensitive, Fisher offers theHIGH-SEAL graphite packing system (figure 7). TheHIGH-SEAL packing system provides superiorsealing at pressure/temperature ratings beyondENVIRO-SEAL limits. ENVIRO-SEAL systems mayalso be applied for superior stem sealing in higherpressure/temperature applications not requiring EPAcompliance.

ENVIRO-SEAL packing systems, available withPTFE, graphite, or Duplex packing, and theHIGH-SEAL graphite packing system featurelive-loading and unique packing-ring arrangementsfor long-term, consistent sealing performance.

NACE Standard MR0175 Compliance

Standard procurement procedures andmanufacturing processes used by Fisher assure thatcontrol valves with sour service trims comply withthe chemical and physical requirements of NACEstandard MR0175. Incoming raw materials areselected for sour service trims by specificationscovering chemical composition, forming, hardness,heat treatment, and finish. In addition, thesubsequent machining, welding, and heat treatmentof the materials being processed into finished partsis strictly regulated by manufacturing standards.

Due to strict start-to-finish manufacturing qualitymanagement, Fisher offers a high degree ofconfidence that the parts and assemblies providedfor sour service will comply with MR0175.Additional testing and documentation to assurecompliance with MR0175 is not required, in mostcases. However, in cases where documentation isrequired, the following items 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 veryspecific and the application of the standard to controlvalve materials is quite complex. There are,however, some general guidelines that are alwaysfollowed:

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

� Martensitic and cast precipitation hardeningstainless steel are not used.

� Control valve packing sets are jam style only.

� Valve stems are made from S20910 (Nitronic50).

� Primary trim materials are S31600 and alloy 6.

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

� No machining operations that cause workhardening of the materials are performed in themanufacturing process.

� Plating and coatings are used only oversuitable base metals and are not intended forcorrosion protection.

� Bolting in NACE MR0175 (non-exposedbolting) material is provided as standard. Bolting inNACE MR0175 (exposed bolting) material isavailable as an option. See table 12.

Fisher does not assume responsibilityfor the selection, use, or maintenanceof any product. Responsibility forproper selection, use, andmaintenance of any Fisher productremains solely with the purchaser.

1. DIN (or other) ratings and end connections can usually be supplied; consult your Fisher sales office.2. The pressure/temperature limits in this bulletin and in any applicable standard limitations should not be exceeded.3. 316 stainless steel (CF8M) valves with SA-193-B7 bonnet bolting are capable of the full Class 600 rating through 427�C (800�F). For higher temperatures or for other bolting materials, thevalve may have to be derated. Contact your Fisher sales office for further information. Also note that the ANSI standard does not allow the use of intermediate ratings for flanged valves.4. Limitation based on excessive noise increases if max �P/P1 ratio for a given cage level is exceeded.

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, reversing the ENVIRO-SEAL PTFE packing rings is not necessary.
