Valves are mechanical devices to control fluid or gas applications and they come in various types thus bellow valves are part of them. When theheavy material of hazards chemicals and alarge variety of toxic materials are being used In industries the pipelines need to be secured with bellow valves to get a safe side from leakage of such material which can cause damage to plant operators or the environment. If air enters through the glands leakage it could result in amassive explosion to both humans and nature.
the bellow valves help in reduction of gas leakage from gland components
The energy loss due to leakage is controlled which helps to control global warming and hence protecting the environment
From lab experiments, it has concluded that bellow valves have a very low and minor degree of leakage
Special safety measures are suited by the valves for flammable liquids, toxic and odor liquids,
The valves give less stress to maintain as they are effective and reduce maintenancecost because the gland packing does not need to be regularly retorqued.
The stems of valve and gland components are sealed with bellows to prevent contact with liquid in pipes,
