Bellow Seal Valve (UBGB-CT02 / UBGB-FT02): Zero-Leakage Fluid Isolation

Eliminating fugitive emissions and gland packing leaks is critical when conveying high-temperature thermal fluids, toxic chemicals, and hazardous gases. The Uni Klinger Bellow Seal Valve (UBGB-CT02 / UBGB-FT02) provides a hermetically sealed barrier between the process media and the atmosphere, ensuring complete containment and environmental safety.

Engineered to strict ASME B16.34 design standards, these valves replace standard stem packing with a flexible metallic bellow mechanism, making them ideal for high-risk applications where zero leakage is mandatory.

Key Features & Advantages

• Hermetic Stem Sealing: Flexible metal bellows form an impenetrable seal around the stem, completely eliminating gland leakage and fugitive emissions.
• High-Temperature Capability: Built to perform continuously in extreme thermal fluid and hot oil environments exceeding 300°C.
• Flexible Product Variants: Available in UBGB-CT02 and UBGB-FT02 configurations to match specific flange face standards and piping arrangements.
• Dual Containment Safety: Features a secondary stuffing box with emergency gland packing above the bellows for added system security.
