1 ENVIRO- seal and HIGH-SEALP acking Systems for Sliding-Stem valves ( Live-Loaded ) fisher ENVIRO- seal and HIGH- seal live-loadedpacking systems offer exceptional stem sealingcapabilities. These systems easily install in yourexisting valves or can be purchased with new and HIGH- seal packing systems helpseal your process to conserve valuable process fluidand protect the environment against the emission ofhazardous or polluting fluids. The long life andreliability of these systems also reduce yourmaintenance costs and process control applications requiring compliancewith mandated environmental protection regulations,the unique ENVIRO- seal packing system and, forhazardous service, the ENVIRO- seal bellows sealsystem are offered.

2 These packing systems keepfugitive emission concentrations below the 100 ppm(parts per million) requirement set by the federalEnvironmental Protection Agency (EPA).The HIGH- seal packing system (figure 1) providesexcellent sealing at pressure/temperature ratingsbeyond ENVIRO- seal ENVIRO- seal and HIGH- seal packing systemsfeature live-loading and unique packing-ringarrangements for consistent, long-term sealingperformance. The ENVIRO- seal packing system isavailable in double PTFE, graphite ULF, and duplexconfigurations. The HIGH- seal packing system isoffered without PTFE washers (graphite composite),for nuclear applications where PTFE is prohibited, andwith PTFE washers (graphite ULF) for all easy-e Valve Bonnet with ENVIRO- seal Packing InstalledVALVEBONNETBELLEVILLESPRINGSVAL VESTEMPACKINGFLANGEPACKINGFOLLOWERW5814- 1*Featuresn Compliance with the Clean Air Act-- The excellentstem sealing of the ENVIRO- seal packing system(figure 1) controls emissions to below the EPAminimum of 100 ppm (parts per million).

3 ENVIRO- seal packing systems provide an excellentstem seal to help prevent the loss of process Improved Service Life-- ENVIRO- seal andHIGH- seal packing systems, coupled with a verysmooth stem surface and live-loading, give you longservice life with very low maintenance. Thelive-loading provides a constant load over the life ofthe packing material.

5 See table 2 for a list of applicable producttypes and stem Duplex packing systems weredeveloped, utilizing the benefits of both PTFE andgraphite components. These special packing systemsprovide the capability of graphite packing along withlow friction advantages of PTFE packing. Thus,ENVIRO- seal Duplex packing systems provide a lowfriction, low emission, fire-tested solution forapplications with process temperatures below 232_C(450_F). ENVIRO- seal Duplex packing systems weretested in accordance with API Standard 589, Fire TestEvaluation of Valve stem Packing , first H2 DuplexENVIRO- seal H2 Duplex packing systems (figure 1)were developed for high pressure applicationsrequiring low emission performance at pressures up to138 bar (2000 psig) and temperatures up to 149_C(300_F).
