One of the most frequent and serious problems valves face is gland leakage, results in wasted and increased plant downtime. Apart from the high cost of energy losses, Gland leakages can also cause serious environmental, ecological and health hazards to plant workers and personnel.
Bellow Seal Valves
Very common. Due to friction between stem occurs within a few cycle no matter which make valve or quality of gland packing;
Considerable amount through gland leakages. Normally large amount when leakage remains unattended.
