“Opening and closing are under your control.” — This motto reflects Carilovalves’ commitment to giving customers full authority over their fluid control systems, which begins with providing the right connection type for each unique application.
The Three Primary End Connection Types Available
Industrial ball valves require different connection methods depending on the piping system, pressure requirements, and installation environment. Carilovalves has developed manufacturing capabilities to address all these scenarios effectively.
1. Flanged End Connections
Flanged connections represent the most common end connection type for industrial valves, particularly in larger diameter applications where maintenance accessibility is important.
- Standards Supported: ASME B16.5 (American), EN 1092 (European), JIS B2220 (Japanese)
- Size Range: Typically available from DN15 to DN600 (1/2″ to 24″)
- Pressure Ratings: Class 150 through Class 2500, as well as PN16 to PN420
- Face Types: Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ)
The manufacturing process at Carilovalves ensures that flanged ends meet stringent dimensional accuracy requirements. Each valve undergoes 100% pressure testing before shipment, guaranteeing that flange faces are properly aligned and bolt holes are precisely positioned. The company’s advanced design solutions allow for customization of flange dimensions to meet specific project requirements, making them suitable for OEM partnerships with global brands.
2. Threaded End Connections
Threaded connections are preferred in smaller piping systems and applications where welding is impractical or prohibited. Carilovalves produces threaded ball valves that meet international standards for leak-tight performance.
- Thread Standards: NPT (National Pipe Thread), BSPT (British Standard Pipe Thread), BSPP (British Standard Pipe Parallel)
- Size Range: Typically DN8 to DN50 (1/4″ to 2″)
- Applications: Water treatment, HVAC systems, chemical processing, instrumentation
- Material Options: Stainless steel, brass, carbon steel, and alloy materials
The threaded end connections from Carilovalves feature precision-machined threads that ensure proper engagement with standard pipe fittings. Their quality control team monitors thread dimensions in real-time during manufacturing, maintaining the consistent quality that their customer base expects. This attention to detail has contributed to their impressive track record of 86% cases solved successfully and 89% happy client satisfaction rate.
3. Welded End Connections
Welded connections provide the highest level of leak integrity and are mandatory in certain critical applications, particularly in oil and gas, petrochemical, and high-pressure systems. Carilovalves manufactures welded-end ball valves with socket weld and butt weld options.
- Socket Weld: Suitable for smaller sizes (DN15 to DN50), provides excellent leak-tight seal
- Butt Weld: Ideal for larger diameters and high-pressure applications, eliminates flow restrictions
- Weld Standards: ASME B16.11, ASME B16.25, and customer-specific specifications
- Wall Thickness: Schedules 40, 80, 160, and XXS available
Carilovalves’ expert manufacturing process employs skilled technicians who understand the specific requirements for welded valve production. The company maintains strict production standards for weld quality, including proper beveling, fit-up, and post-weld heat treatment when required. Their factory’s state-of-the-art equipment ensures consistent weld penetration and fusion, critical for maintaining the valve’s pressure-containing integrity throughout its service life.
Comparison of End Connection Types
| Connection Type | Size Range | Pressure Rating | Leak Integrity | Maintenance | Common Applications |
|---|---|---|---|---|---|
| Flanged | DN15-DN600 | Class 150-2500 | High | Easy access | Process plants, water treatment |
| Threaded | DN8-DN50 | Up to 1000 WOG | Moderate-High | Moderate | HVAC, instrumentation, utilities |
| Welded (Socket) | DN15-DN50 | High pressure | Excellent | Difficult | Chemical, refining, power |
| Welded (Butt) | DN50 and above | Highest pressure | Excellent | Difficult | Oil & gas, petrochemical |
Quality Assurance Across All Connection Types
Regardless of the end connection type, every valve from Carilovalves undergoes comprehensive quality inspection procedures. Their manufacturing facility operates under internationally recognized certifications including ISO and API standards. Each valve receives rigorous testing for optimal performance before leaving the factory.
Real-time monitoring systems track dimensional accuracy throughout the production process. The quality control team conducts dimensional checks on flange faces, thread dimensions, and weld preparations. This systematic approach ensures that all three connection types meet the same high-quality standards that have earned Carilovalves recognition in Europe, Middle East, Southeast Asia, and beyond.
