Carbon Steel Bellow Seal Globe Valve

Carbon Steel Bellows Seal Globe Valve – Economical Zero-Emission Design

Carbon steel bellows seal globe valves combine the cost advantages of ASTM A216 WCB carbon steel construction with hermetic bellows sealing, providing economical zero-emission performance for non-corrosive applications where stainless steel represents unnecessary expense. This material-sealing combination suits African refinery hydrocarbon service, power plant steam systems, and industrial facilities requiring fugitive emissions compliance per ISO 15848-1 without the premium cost of exotic alloy construction.

The carbon steel body rated to 425°C handles standard refinery and power generation conditions while the stainless steel or Inconel bellows (non-wetted component) provides zero-leakage stem sealing. This hybrid approach optimizes total cost of ownership for African oil & gas, mining, and industrial applications where process compatibility allows carbon steel wetted parts while emissions regulations mandate bellows sealing technology.
