We supply high-quality fully welded ball valves and extended stem ball valves designed for reliable shut-off and flow control in demanding pipeline applications. These valves are widely used in the oil & gas, petrochemical, natural gas, district heating, refinery, and energy industries. Fully welded ball valves feature a welded body construction designed to minimize external leakage points, while extended stem ball valves provide access to valve operation when the pipeline is buried, insulated, or installed below ground level.
Key Features:
- Fully welded body and end—zero external leak paths
- Full bore design for pigging and minimum pressure drop
- Trunnion mounted ball for low operating torque
- Extended stem for underground and remote location operation
- Complete bypass system integrated as standard
- Stem and seat sealant injection for in-service maintenance
- Anti-blow-out stem for maximum safety
- Fire safety design compliant
- Transition pups available on request
- Size range: 2″ ~ 48″ (DN50 ~ DN1200)
- Pressure classes: CL150 ~ CL2500
- Materials to ASTM & API 5L standards
