• Temperature:
◦ Soft Seal: -29℃～180℃
◦ Hard Seal: Up to 450℃ (down to -196℃)
• Material:
◦ Valve Body/Goblin: A105, WCB, 304, 316, 316L, Alloy Steel
◦ Ball: 304, 316, Hard Chrome Plated, Tungsten Carbide Coated
◦ Seal: PTFE, Reinforced PTFE, PPL, Metal Seal
• Actuation: Manual, Pneumatic, Electric, Hydraulic, Turbine Drive
• Standards: GB/T 12234, API 600, API 6D
Working Principle: Rotate the sphere 90°: If the sphere's through-hole is aligned with the pipeline, it is fully open; if perpendicular, it is fully closed, quickly cutting off or connecting the medium.
Applicable Scenarios:
• High-pressure conditions: Oil and gas, coal chemical industry, long-distance pipelines, deep-sea oil and gas.
• High-temperature corrosion: Chemical acids and alkalis, steam, heat transfer oil, high-temperature gases.
• Harsh environments: Shipbuilding, power generation, metallurgy, cryogenic LNG transportation.
• Frequent operations: Automated control, skid-mounted equipment, process pipeline cutoff/regulation.
