TBSV – Bellow Seal Isolation Valves for Steam, Condensate & Thermic Fluid Systems

TBSV Bellow Seal Isolation Valves

TBSV (Thermax Bellow Seal Valves) are high-performance, zero-leakage isolation valves specially designed for steam, condensate, thermic fluid and various industrial fluid systems. With metallic bellows welded to the valve stem and bonnet, TBSV creates a hermetic seal, ideal for high-pressure and high-temperature applications.

Key Features of TBSV

  • Zero Leakage Design – metallic bellows ensure an impermeable seal
  • Low Pressure Drop – engineered for minimal pressure loss
  • Stellite-Coated Internals for enhanced hardness and superior erosion resistance
  • Long Service Life of valve internals
  • Improved Throttling Control for precise flow regulation

Applications of TBSV Valves

  • Steam Distribution Systems
  • Condensate Return Lines
  • Thermic Fluid Circulation
  • Gas and Water Lines
  • Power Plants and Refineries
  • Process Heating Systems

Benefits of TBSV Bellow Seal Valves

  • Prevents fugitive emissions and media leakage
  • Ensures safe and reliable isolation in high-temperature systems
  • Reduces maintenance frequency and downtime
  • Long-term performance in corrosive and erosive environments
  • Ideal replacement for conventional gland-packed valves
