TECHNICAL DATA SHEET
PRODUCT: 3-Piece Floating Ball Valve
MODEL / REFERENCE: 1/2″-600LB-SW
TYPE: Full Port, Floating Ball, Bolted Body Construction
1.0 PRODUCT DESCRIPTION & APPLICATION
A high-pressure, compact 3-piece ball valve designed for reliable shut-off service in demanding industrial applications. The three-piece bolted construction allows for easy in-line maintenance, seat replacement, and cleaning without removing the valve from the pipeline. Featuring Socket Weld (SW) ends on both sides, it provides a robust, leak-resistant connection ideal for permanent installations in high-pressure systems. This valve is commonly used in instrumentation, sampling systems, high-pressure chemical injection, utility lines, and other critical services within oil & gas, petrochemical, and power generation industries where integrity and maintenance ease are paramount.

6.0 KEY DESIGN FEATURES
- 3-Piece Bolted Design: Enables easy disassembly for maintenance, seat replacement, and system cleaning without pipeline removal.
- Dual Socket Weld Ends: Provide a permanent, high-strength, leak-free connection superior to threaded fittings in high-vibration and high-pressure service.
- Full Port Design: Minimizes pressure drop and allows for pigging in some applications.
- Floating Ball Design: Process pressure assists in sealing by pushing the ball against the downstream seat.
- Integral Anti-Static Device: Ensures safe dissipation of static electricity.
- Blow-Out Proof Stem: Securely retained by a shoulder or insert, preventing ejection under pressure.
7.0 TESTING & INSPECTION
- Hydrostatic Shell Test: Per API 598. Test pressure: 1.5 x 600 = 900 psi (water).
- Test d'étanchéité du siège : Per API 598. Test pressure: 1.1 x 600 = 660 psi (air or water).
- High-Pressure Gas Test: Optional for sensitive applications.
- Material Certification: Mill Test Reports (MTRs) available for body materials.
- Documentation: Certificate of Conformance (COC) supplied with each valve.
8.0 INSTALLATION & MAINTENANCE NOTES
- CRITICAL: The valve must be fully open during welding of socket weld ends to prevent heat damage to internal seals (seats, stem packing).
- Ensure pipe ends are clean, square-cut, and inserted to the proper depth within the socket weld cavity.
- Follow standard socket weld procedures (ASME B31.3) for best results.
- For disassembly, completely depressurize the line before loosening the two body bolts.
9.0 OPTIONS & ACCESSORIES
- Actionnement : Pneumatic (double-acting/spring-return), Electric actuators.
- ISO 5211 Mounting Pad (Standard or optional) for direct actuator mounting.
- Gear Operator for high-cycle applications.
