BELLOW SEAL ISOLATION VALVES
TBSV – Bellow Seal Isolation Valves for Steam, Condensate & Thermic Fluid Systems

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
