1″-800LB-Nipples 3 Piece Vacuum Ball Valve

Technical Data Sheet

Product: 3-Piece Vacuum Ball Valve with Nipples
Model / Size: 1″ – 800LB – Nipples
Configuration: Three-piece body construction with integral nipples (socket weld or butt weld ends) for vacuum service

1. Product Description

This valve is a three-piece ball valve specifically designed for vacuum service, featuring integral nipples (short pipe extensions) welded or integrally formed on both ends. The three-piece construction allows for easy in-line maintenance without removing the entire valve from the piping system. The valve is rated for Class 800LB pressure, making it suitable for high-pressure vacuum applications, gas handling, and critical process systems where absolute leak integrity is required. It is ideal for vacuum systems, high-purity gas lines, and high-cycle applications where reliable shut-off is essential.

8. Features & Benefits

1. Vacuum Service Optimized: Low outgassing materials, helium leak-tested, and precision-machined components ensure high vacuum integrity.
2. Three-Piece Construction: Allows for in-line maintenance – end caps can be removed to access ball and seats without disturbing pipe connections.
3. Integral Nipples: Pre-welded or integrally formed nipples simplify field installation, reducing welding points and potential leak paths.
4. High Pressure Capability: Class 800 rating suitable for high-pressure gas and liquid systems, including hydraulic and pneumatic applications.
5. Tight Shut-Off: PTFE or PEEK seats provide zero-leakage sealing in both directions.
6. Low Operating Torque: Smooth ball and seat surfaces ensure easy operation, even under differential pressure.
7. Locking Handle (Optional): Prevents unauthorized operation – essential for safety-critical systems.
8. Fugitive Emission Compliance: Stem sealing can be designed to meet ISO 15848 or TA-Luft standards.

9. Important Notes

• Vacuum Service: For ultra-high vacuum (UHV) applications, specify metal seats and bellows stem seal to achieve leakage rates below 1×10⁻⁹ Pa·m³/s.
• Installation: The valve may be installed in any orientation. Ensure proper support for piping to avoid stress on the valve body.
• Cleaning: For oxygen service or high-purity vacuum applications, the valve must be specified with degreasing and cleaning per ASTM G93 or CGA G-4.1.
• Nipple Ends: Confirm whether nipples are socket weld (SW) or butt weld (BW) to match piping specifications. Socket weld nipples require fillet welding; butt weld nipples require full penetration butt welds.
• Maintenance: When replacing seats or seals, use manufacturer-approved kits to maintain vacuum integrity.
• Material Compatibility: Verify seat and seal materials are compatible with the process media to prevent swelling, degradation, or outgassing.

If you require additional specifications such as NACE MR0175, oxygen cleaning, high-temperature bellows seal, or actuator mounting, please let me know and I can supplement the data sheet accordingly.
