Our forged steel self-sealing butt welding globe valves feature innovative pressure-assisted sealing technology that automatically enhances sealing performance as system pressure increases. Engineered for precise flow regulation in critical process systems, these valves combine butt weld ends (ASME B16.25) with premium forged construction (ASTM A105/A182) for superior reliability in high-pressure, high-temperature applications.
✔ Pressure-Activated Sealing – Auto-enhancing stem and seat seals
✔ Zero Emissions Design – Meets ISO 15848-1 fugitive emission standards
✔ Fire-Safe Construction – API 607 compliant options available
✔ Precision Flow Control – Excellent throttling characteristics
✔ Maintenance-Free Operation – Self-compensating wear mechanism
