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.

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).
- Test d'étanchéité du siège : 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 à 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
- Actionnement : 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)
