1/2″-600LB-SW 3 Piece Floating Ball Valve

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.

2.0 DESIGN & STANDARDS

• Design & Pressure Rating: ASME B16.34, Class 600
• End Connection: Socket Weld (SW) per ASME B16.11
• Face-to-Face Dimensions: Compliant with standard industry dimensions for 3-piece valves.
• Fire Safe Design: API 607 / ISO 10497 (Optional)
• Anti-Static Device: API 608 / ISO 17292 (Standard)
• Blow-Out Proof Stem: API 608 (Standard)

3.0 GENERAL SPECIFICATIONS

4.0 PRESSURE-TEMPERATURE RATINGS

• Rated per ASME B16.34 for Class 600. The maximum allowable pressure varies with temperature and material.
• Example (CF8M/316SS Body with PTFE Seats): 1440 psi @ 100°F (38°C), ~285 psi @ 450°F (232°C). Consult detailed P-T chart for specific materials.

5.0 MATERIALS OF CONSTRUCTION (STANDARD)

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).
• Seat Leak Test: 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

• Actuation: Pneumatic (double-acting/spring-return), Electric actuators.
• ISO 5211 Mounting Pad (Standard or optional) for direct actuator mounting.
• Gear Operator for high-cycle applications.
• Locking Device for handle.
• Stem Extension for insulated lines.
• Cavity Pressure Relief / Drain Port.
• Fire-Safe Design with secondary metal seals (per API 607).
• Special Trim Materials (Hastelloy, Monel, Stellited surfaces).
