Description

BELLOW SEALED GLOBE VALVE

Overview

The bellows sealed globe valve is a high-performance fluid control device utilizing a metal bellows as its core sealing element, effectively resolving stem leakage issues common in traditional valves. Designed for demanding conditions, it is suitable for high-temperature, high-pressure, toxic, or precious media pipelines, ensuring long-term stability and zero-leakage safety standards.

Features

· Dual Sealing: Combines static bellows sealing with dynamic packing sealing to minimize leakage risks.

· Extreme Condition Resistance: Withstands temperatures from -196°C to +550°C and pressures up to 10MPa, compatible with corrosive media.

· Low Maintenance: Bellows structure reduces friction wear, extends service life, and lowers replacement frequency.

· International Compliance: Designed per API 602, ASME B16.34, ensuring safety and compatibility.

· Flexible Configuration: Available with flanged or welded connections, materials include stainless steel and alloy steel.

Applications

· Petrochemical: Hazardous media control in refining and cracking units.

· Pharmaceutical: Sterile pipeline systems preventing cross-contamination.

· Nuclear Power: Cooling systems and fluid management in radioactive environments.

· Special Gases: High-purity gas transmission and storage.
