Bellows globe valve
This bellows globe valve (also named bellows seal globe valve) is a high-performance industrial shut-off and regulating valve, designed and manufactured in strict compliance with ASME B16.34 and ANSI international standards. It adopts an integrated metal bellows seal structure to completely eliminate stem leakage risks of traditional globe valves, with standard ASME B16.5 flanged connection and full size range from DN15 to DN400 (NPS 1/2" to 16").

Product Overview
Core Product Features
- Dual Seal Zero-Leakage Design
Adopts thickened 316 stainless steel bellows + high wear-resistant packing dual seal system, meeting ANSI B16.104 Class VI zero-leakage standard. It completely solves the common pain points of stem wear and medium leakage of traditional globe valves, greatly extending service life and complying with global environmental and safety regulations.
- Precise Throttling & Stable Operation
Classic streamlined flow channel design with precision ground valve plug and seat, realizing stepless and stable flow and pressure regulation. It opens and closes smoothly without jamming, vibration or noise, effectively avoiding water hammer, with better regulation performance than conventional gate valves.
- Multi-Material Customization, Wide Adaptability
Valve body and wetted parts can be customized with ASTM standard materials: ductile iron, WCB carbon steel, 304/316 stainless steel. It is compatible with water, steam, thermal oil, oil products, weak corrosive media and food-grade fluids, covering conventional to mildly corrosive working conditions.
- Standard ASME Flanged Connection, Full Size Coverage
Standard ASME B16.5 RF flanged end with unified dimensional specifications, directly compatible with overseas standard flanged pipeline systems without modification. Full size range from DN15 to DN400, perfectly adapting to small-bore precision pipelines and large-bore main pipelines.
- Easy Operation & Low Maintenance
Equipped with non-slip labor-saving handwheel for smooth manual operation, no external power supply or air source required. Compact structure with no quick-wear parts, no complicated daily maintenance needed, greatly reducing the full life cycle operation cost.
- Full Standard Compliance, Global Universal
Full production process from design to testing follows international industrial valve standards. Each valve undergoes strict hydraulic and pneumatic seal tests before delivery, fully adapting to the procurement standards and working conditions of overseas customers worldwide.
