The fully welded ball valve features an integral forged steel welded body with liquid penetrant testing performed on weld joints. Carbon steel components undergo electroless nickel plating treatment. Equipped with a mirror-polished stainless steel ball, pre-loaded spring seat rings, and blowout-proof stem design, it supports manual, gear, electric, or pneumatic actuation.
The dual-seat design enables independent fluid shutoff, providing double block-and-bleed functionality, while the single-welded joint structure optimizes manufacturing efficiency and sealing reliability. The product complies with API 608, API 6D, and other design standards, with connection ends conforming to ASME B16.5 specifications.

Features:
Fully welded ball valve ensures zero external leakage.
The ball is precision-machined under advanced computer-controlled inspection, guaranteeing high machining accuracy.
Made of the same material as the pipeline, it eliminates stress concentration and deformation caused by earthquakes or ground traffic, with excellent aging resistance.
The sealing ring is made of 25% carbon-loaded RPTFE, ensuring 100% leak-proof performance.
Direct-buried design eliminates the need for large valve pits; only small surface access pits are required, significantly reducing construction costs and time.
The valve body length and stem height can be adjusted according to pipeline design requirements.
The ultra-precise ball machining ensures smooth operation without interference.
Constructed with premium materials, it withstands pressures exceeding PN25.
Compact and aesthetically designed compared to industry counterparts of the same specification.
Minimum 20-year lifespan under normal operating conditions.
