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).
  • Испытание на герметичность седла: 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.
  • Лицом к лицу: 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

  • Приведение в действие: 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
