FIELD REPAIR
Regular maintenance of the total system is recommended to assure sustained performance.
See Figure-4 and Table-7 for maintenance kits and their part numbers.
Caution: Before loosening or removing packing cartridge, depressurize valve to zero psi
gauge (0 psig). If the packing cartridge is loosened or removed while there is pressure in
the valve, valve packing may blow out with the potential of bodily injury and/or water/steam
damage.
Caution: EPDM components are not compatible with petroleum-based compounds. Use
of such compounds will damage packings and seat rings and necessitate replacement of
packing cartridge and/or stem and plug assembly.
