Description
L&T CS Ball Valves with socket weld ends are designed for high-pressure, leak-proof piping systems. These valves are compact, durable, and ideal for small-bore pipelines where welded connections are preferred over flanged or threaded joints. They provide bubble-tight shutoff with reliable long-term performance.
Design & Construction
- Type: Floating Ball Design
- Construction: Single-piece / Two-piece / Three-piece
- Operation: Quarter-turn (90°)
- Sealing: Soft-seated (PTFE / RPTFE) or metal-seated options
- Line pressure pushes the ball against the seat for tight sealing
End Connection – Socket Weld
- Ends conform to ASME B16.11 (Socket Weld standard)
- Pipe is inserted into socket and fillet welded for permanent joint
- Provides leak-proof, rigid connection suitable for high pressure & vibration
- No need for flanges or threading → compact installation
- Ideal for small diameter pipelines
Material of Construction (MOC)
- Body: Cast Carbon Steel (ASTM A216 Gr. WCB)
- Ball: Stainless Steel / Hard-faced
- Stem: SS 410 / SS 316
- Seats: PTFE / RPTFE / Metal (optional)
- Seals: Graphite / PTFE
Pressure Ratings
- ASME Class: 150 / 300 / 600
- Suitable for low to high pressure services
Size Range
- Typically 15 mm (½”) to 100 mm (4”)
- Available up to 200 mm (8”) depending on design
Temperature Range
- –29°C to +200°C (soft seated)
- Up to +400°C (metal seated options)
Key Features
- Blow-out proof stem for safety
- Fire-safe design (API 607 / ISO 10497)
- Anti-static device
- Low operating torque
- Compact & lightweight design
- High integrity stem sealing
- Full bore / reduced bore options
- Actuator mounting flange (optional)
Advantages of Socket Weld End
✔ Strong, permanent joint
✔ Zero leakage chances at joints
✔ Suitable for high-pressure & high-temperature lines
✔ Less maintenance compared to threaded joints
✔ Compact system layout (no flange space required)
Applications
- Oil & Gas pipelines
- Chemical & Petrochemical plants
- Power plants
- Utility & process lines
- Steam and condensate systems
- Hydraulic and high-pressure services
Summary
L&T CS Socket Weld Ball Valves are best suited for compact, high-pressure piping systems where welded connections ensure maximum strength, zero leakage, and long service life. They are widely used in critical industrial applications requiring reliability and safety.
