LFE PACKING
• Low Fugitive Emission packing – LFE
• Live Loading using additional disc springs eliminates
frequent retightening of gland packing
• Zero emission packing – This packing is even
recommended for critical services also. For eg,
chlorine, ammonia etc. Low cost, high performance
packing
• LFE is specifically recommended in control valves
subjected to Thermal Cyclic Loading.
