Bellow Seal Globe Valves

Zero-emission stem sealing for hazardous, toxic, and high-purity media across chemical and power applications.

Engineered for Zero Stem Leakage in Critical Service

Conventional gland-packed valves leak. For hazardous, toxic, or high-value media, even a slow stem weep is unacceptable. Our bellow seal globe valves replace gland packing with a hermetically welded stainless or Inconel bellow assembly, giving you a hermetically sealed stem path that meets TA Luft and ISO 15848 fugitive emission limits.

Every bellow seal valve we supply includes a backup gland packing arrangement — if the bellow ever fails, the valve remains tight in service until scheduled replacement. Stocked in carbon steel, stainless 316, and chrome-moly across DN 15 to DN 200, ANSI 150 through 600.
