API ASME BS DIN API6D DN15-DN1000 Carbon Steel SS Wcb CF8 Anti-Explosion Ball Valve delivers reliable flow control for oil, gas, and industrial systems. It features WCB/316 materials, Class 150 ~ 600 pressure rating, fire-safe (API 607) and anti-static protection, complying with global standards. Customizable in size (DN15-DN1000), seat type (soft/metal), actuation (manual/electric/pneumatic), and DBB functionality to meet specific pipeline, refinery, or gas processing needs.
TIANYU Thermal Insulation Jacketed Ball Valve Steam Stainless Steel Flange Ball Valve high-quality thermal insulation jacketed ball valve, with floating ball design and flanged connections, ensures reliable control of high-viscosity, high-temperature media. Its jacketed structure prevents solidification, while robust materials and seals extend service life. Ideal for petroleum, chemical, and pharmaceutical sectors. Customizable in materials (WCB/CF8), jacket type, and actuation to meet specific thermal and operational needs.
Fully Welded Ball Valves

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.
