The cast steel globe valves with bellows do not need any maintenance. The bellow in stainless steel 304 avoids any contact between the fluid and the stem, for this reason the valves are free from maintenance. The bellow is granted for 8000 movements. The bellow sealed globe valves are suitable for severe services, such as diatermic oils, steam and flammable fluids.
