Fully Welded Ball Valves

What is a Fully Welded Ball Valves？

Fully Welded Ball Valves fuse body components via welding, offering high strength, tight sealing, and long life for high-pressure/large-diameter/harsh pipelines.

Core Features

All-Welded Structure: No flanges/bolts, eliminating external leaks via butt/socket welding.
Self-Tightening Seal: Pressure-driven seating ensures bidirectional sealing (DBB).
Safety Compliance: API 607 fire-rated with anti-static design.

Fully Welded Ball Valves: Core Advantages

Zero External Leakage: All-welded design eliminates flange/thread leaks, ideal for flammable/toxic/high-value media like natural gas.
Extreme Environment Ready: Forged steel/stainless steel bodies (Class 2500, -60°C~450°C) suit long pipelines, subsea, and harsh climates.
Low Maintenance & Long Life: No external seals, hardened ball surfaces (e.g., nickel-phosphorus coating) ensure 20+ years of corrosion-resistant use.
Rapid-Action Automation: 90° rotation with electric/pneumatic actuators for remote SCADA-compatible control.

Typical Application Scenarios of Fully Welded Ball Valves

Oil and Gas Industry: Main valves for long-distance pipelines, city gas gate stations, subsea gas transmission pipelines.
Chemical and Energy Sectors: High-pressure hydrogenation units, liquefied natural gas (LNG) transportation, steam pipelines in thermal power plants.
Marine Engineering and Shipbuilding: Ship ballast water systems, oil and gas processing pipelines on offshore platforms.
Municipal and Industrial Water Supply: High-pressure water transmission main lines, large-diameter shut-off valves for circulating water systems.
