Fisher EZ Sliding Stem Control Valve - Emerson

1 EZ Sliding - stem Control ValveFisher EZ valves (figure 1) are used for throttling oron-off Control of a wide variety of liquids and single-port, globe-style body design offersquick-change trim and a post-guided, unbalancedvalve plug. The EZ Valve is used in chemical orhydrocarbon processing applications or wherevercontrol of non-lubricating, viscous, or otherhard-to-handle fluids is seating is standard for all generalapplications over a wide range of pressure drops andtemperatures. Metal-to-PTFE seating is optional forstringent shutoff easy-et Valve FamilyEZ Valve bodies are part of the versatile easy-e family ofindustrial Control valves .

2 Easy-e Valve bodies share thefollowing characteristics:n Multiple trim material choicesn Trim temperature capability with standard metalseats to 427_C (800_F)n FGM gasketsn Interchangeable, restricted-capacity trims andfull-sized trims to match variable process flowdemandsn Different Valve plug styles that provide particularflow characteristics for highly-specializedapplications. Standard plugs are available with thefollowing flow characteristics:n quick-openingn linearn equal percentageW2174-2 Fisher EZ Valve with 657 Actuatorn Optional constructions allow material compatibilitywith NACE MR0175 / ISO 15156 and your Emerson sales office or Local BusinessPartner for 316 stainless steel packing box parts are standard(including packing flange, studs, and nuts)EZ ValveD100025X012 Product.

3 EZOctober 2017EZ ValveD100025X012 Product BulletinOctober 2017 2 Featuresn Trim Designed for Stability-- Post guiding providesvalve plug stability with less chance of a stickingvalve plug due to non-lubricating or sticky processfluids or build-up of entrained solids. Post guidingstabilizes the Valve plug at all points in its travelrange to reduce vibration, mechanical noise, andtrim Compliance with the Clean Air Act-- ENVIRO-SEAL packing systems (figure 3) that provide animproved stem seal to help prevent the loss ofprocess fluid are available.

4 These packing systemsfeature PTFE, Graphite ULF, or duplex packing withlive-loading for reduced packing Sour Service Capability-- Unless otherwise noted,references are to NACE MR0175-2002. Optionalmaterials are available to meet NACE MR0103 andNACE MR0175 / ISO 15156. Material requirementsunder these standards vary by edition and year ofissue; the specific standard must be Compliance with European Standards-- valves areavailable with dimensions specified by EN/DINstandards. See figure Reliability-- The process fluid flows through thetrim, flushing away solid deposits above and belowthe guide bushing, thus reducing the possibility of asticking Valve Easy Maintenance-- Quick-change trim, with aclamped-in seat ring, reduces the disassembly Valve body can stay in the pipeline duringremoval of trim parts for inspection Application Flexibility-- Low-flow requirements canbe satisfied with standard restricted-capacity trim orwith Micro-Form, Micro-Flute, or Micro-Flow valveplugs.
