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 . 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.

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. 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.

3 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. If flow requirements change, the Valve can beconverted to full-sized Economy-- Streamlined flow passages providegreater capacities than most globe valves of thesame line of ContentsFeatures Packing System Specifications and HIGH-SEAL Packing Systems and HIGH-SEAL Features Valve Plugs for Minimum Leakage VI Shutoff Capabilities VI Shutoff VI Trim Materials Cross Reference Combinations of Metal Trim Parts Materials & Temperature Limits Body/Trim Temperature Capabilities Selection Guidelines Allowable Pressure Drops Selection Guidelines Allowable Pressure Drops forGasket Materials Flow Coefficients Diameters, Valve Plug Travel, andStem and Yoke Boss Diameters Combinations of Trim Parts Materials and Temperature Limits Information ValveD100025X012 Product :EZOctober 2017 3 SpecificationsValve SizesNPS J1/2, J3/4, J1, J1-1/2, J2, J3, andJ4 End Connection Styles(1, 2)Cast Iron ValvesFlanged.
