    Valves with ENVIRO‐SEAL live‐loaded packing or HIGH‐SEAL Heavy‐Duty live‐loaded packing will not require this initial re‐adjustment. See the Fisher instruction manuals titled ENVIRO‐SEAL Packing System for Sliding‐Stem Valves or Heavy‐Duty Live‐Loaded Packing System (as appropriate) for packing instructions. If you wish to convert your present packing arrangement to ENVIRO‐SEAL packing, refer to the retrofit kits listed in the Parts Kits sub‐section near the end...
  • Page 5 Instruction Manual EZ Valve D100401X012 November 2017 Note If the valve has ENVIRO‐SEAL or HIGH‐SEAL live‐loaded packing installed, refer to instruction manuals ENVIRO‐SEAL Packing System for Sliding Stem Valves, D101642X012, or HIGH‐SEAL Live Loaded Packing System, D101453X012, for packing instructions. Figure 6 shows a typical HIGH‐SEAL packing system. Figures 7 and 8 show typical ENVIRO‐SEAL systems. Figure 3.

  • Page 6: Packing Lubrication

    Instruction Manual EZ Valve D100401X012 November 2017 Packing Lubrication Note ENVIRO‐SEAL or HIGH‐SEAL packing does not require lubrication. If an optional lubricator or lubricator/isolating valve (figure 2) is provided for PTFE/composition or other packings that require lubrication, it will be installed in an optional tapped hole in the bonnet. Use a good quality silicon‐base lubricant.
  • Page 7 Instruction Manual EZ Valve D100401X012 November 2017 If the packing is relatively new and tight on the stem, and if tightening the packing flange nuts does not stop the leakage, the valve stem may be worn or nicked so that a seal cannot be made. The surface finish of a valve stem is critical for making a good packing seal.

    Instruction Manual EZ Valve D100401X012 November 2017 5. Remove the stem/bellows assembly from the soft‐jaw chuck or vise. Place a wrench on the flat areas on the valve stem just below the threads for the actuator/stem connection to keep the stem from turning. Then, unscrew the adaptor (key 24, figure 11), which also includes the valve plug (key 2) or valve plug guide (key 27, figure 13), from the stem/bellows assembly (key 20, figure 11).
  • Page 16 Instruction Manual EZ Valve D100401X012 November 2017 Valves with Plain or Extension Bonnets Perform the following steps to assemble and install the trim. CAUTION To avoid weakening the stem that may cause failure in service, never reuse an old stem with a new valve plug. Using an old stem with a new plug requires drilling a new pin hole in the stem,which will weaken the stem.
