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
연결 종료: 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)

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).
좌석 누출 테스트: 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.
