1-1/4″-600LB-SW 3-Piece Ball Valve

TECHNICAL DATA SHEET

PRODUCT: 3-Piece Ball Valve
MODEL / REFERENCE: 1-1/4″-600LB-SW*NPTM
TYPE: Full Port, Floating Ball, End Entry (3-Piece Bolted Body)

1.0 PRODUCT DESCRIPTION & APPLICATION
A robust 3-piece ball valve designed for reliable on/off service in high-pressure industrial applications. The three-piece bolted body construction (two end caps and a center section) allows for easy in-line maintenance and seat replacement without removing the valve from the pipeline. This model features a Socket Weld (SW) end on one side and a Male NPT (NPTM) threaded end on the other, providing installation flexibility for systems transitioning between welded and threaded piping. Suitable for a wide range of applications including process instrumentation, oil and gas, chemical transfer, power generation, and general industrial services.

2.0 DESIGN & STANDARDS

• Design Standard: ASME B16.34 (Valve Design)
• Pressure Rating: Class 600 (600 LB)
• Socket Weld End: ASME B16.11
• Threaded End: ASME B1.20.1 (NPT)
• Face-to-Face: Compliant with standard industry dimensions for 3-piece valves.
• Fire Safe: API 607 / ISO 10497 (Optional)
• Anti-Static: Per API 608 (Standard)
• Blow-Out Proof Stem: Per API 608 (Standard)

3.0 GENERAL SPECIFICATIONS

4.0 PRESSURE-TEMPERATURE RATINGS

• Rated per ASME B16.34 for Class 600. The maximum allowable working pressure depends on the selected body and seat materials and the operating temperature.
• Example (CF8M Body with PTFE Seats): 1440 psi @ 100°F (38°C), ~285 psi @ 450°F (232°C). Consult detailed P-T chart.

5.0 MATERIALS OF CONSTRUCTION (STANDARD)

6.0 KEY DESIGN FEATURES

• 3-Piece Bolted Body: Enables easy maintenance, seat inspection/replacement, and cleaning without removing valve ends from the pipeline.
• Dual End Connections: Offers versatile installation where welded and threaded connections are required. Socket Weld provides a strong, leak-proof joint. Male NPT allows for straightforward threaded installation.
• Full Port Design: Provides a flow area approximately equal to the pipe ID, minimizing pressure loss.
• Blow-Out Proof Stem: Stem is securely retained, ensuring safety under full pressure.
• Anti-Static Device: Ensures electrical continuity between ball and body.
• Locking Device Tab: On the handle for padlock application (safety isolation).

7.0 TESTING & INSPECTION

• Shell & Seat Pressure Test: Per API 598 / ISO 5208 standard.
• Hydrostatic Shell Test: 1.5 x Class Rating (900 psi for Class 600).
• Seat Leak Test: 1.1 x Class Rating (660 psi for Class 600) with air or water.
• High-Pressure Gas Test: Optional (per customer request).
• Documentation: Certificate of Compliance (COC) with test results. Material Test Reports (MTRs) available upon request.

8.0 DIMENSIONS & WEIGHT

• Socket Weld (SW) End: Prepared per ASME B16.11. Customer must ensure pipe end is prepared correctly for insertion.
• NPT Male (NPTM) Thread: Tapered thread per ASME B1.20.1. Sealant (e.g., thread tape/paste) is required for leak-tight joint.
• Face-to-Face: Standard dimension for 1-1/4″ Class 600 3-piece ball valve. Detailed drawing available upon request.
• Weight: Approximately [e.g., 8-10 lbs / 3.6-4.5 kg] depending on material.

9.0 INSTALLATION & MAINTENANCE NOTES

• Ensure the valve is in the fully open position during welding of the Socket Weld end to prevent heat damage to internal seals.
• Use appropriate thread sealant compatible with the process fluid on the NPTM end.
• For disassembly, relieve line pressure completely before loosening the two body bolts.
• Regular maintenance (cleaning, seal replacement) is simplified due to the 3-piece design.

10.0 OPTIONS & ACCESSORIES

• Actuation: Pneumatic (double-acting/spring-return), Electric, Hydraulic actuators with mounting kits.
• Gear Operator for high-cycle or high-torque applications.
• Mounting Pad / ISO 5211 Top Flange for easy actuator installation.
• Locking Handle / Limit Switch Kit
• Stem Extension for insulation or buried service.
• Drain / Vent Port on the body cavity.
• Fire-Safe Seats & Stem Seals (per API 607)
• Special Materials & Coatings
