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).
좌석 누출 테스트: 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.
대면: 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.
