Zero Leakage Hard Seal Manual Orbit Ball Valve Top Entry Wear-Free for Oil/Gas/Chemical Industry
Orbit design lifts the ball off the seat before rotation, eliminating seat abrasion and ensuring bubble-tight shutoff.
Ball separates from seat before rotation, zero friction on sealing surface, eliminating traditional valve wear; service life extended 3-5x.
Top-entry design enables online maintenance without pipeline removal; maintenance cost reduced by 60%.
Injectable packing for online emission control, eco-friendly and extended seal life.
Body available in WCB, SS304, SS316, CF8, CF8M; forged/cast with deep cryogenic treatment for extreme temperature stability.
Low torque design for easy on-site operation, no power supply required, ideal for remote and explosion-proof environments.
Enables in-line maintenance without removing the valve from the pipeline, saving maintenance time and cost.
Hardened sealing surfaces + anti-corrosion materials, suitable for media with particles, slurry and corrosive fluids.
100% factory pressure test, cryogenic test and performance test; compliant with API 6D, ASME B16.34 standards.
Flange (ANSI/GB/DIN), butt weld, socket weld available to meet different pipeline requirements.
Minimized friction between ball and seat, significantly extends valve life even under frequent operation and harsh conditions.
LNG plants, petrochemical, power plants, natural gas pipelines, cryogenic storage and industrial process systems.
