As a specialized manufacturer of industrial fluid control components, Shanghai Quanbao Electronic Materials Technology Co., Ltd. delivers precision-engineered solutions from our production facilities in Shanghai. Our corrosion-resistant 316 SS ball valve with double ferrule connections represents a significant advancement in high-pressure fluid handling systems, offering unmatched reliability for demanding industrial applications. This valve combines robust construction with leak-proof performance to ensure operational safety and minimize maintenance costs.
Engineered for critical environments, this ball valve features a one-piece body design that eliminates potential leak paths while maintaining full flow capacity. The double ferrule connection system provides superior grip strength and vibration resistance compared to standard fittings, making it ideal for high-vibration machinery and mobile equipment. With a pressure rating of 6000 PSI, it outperforms conventional ball valves in hydraulic, petrochemical, and instrumentation systems where failure is not an option.
Key Technical Specifications:
- Body Construction: Forged 316 stainless steel with integral hard-sealed design
- Sealing Mechanism: PTFE encapsulated stem with secondary metal-to-metal backup
- Flow Efficiency: Full port design (100% bore) minimizes pressure drop
- Operating Temperature: -20°C to 232°C (-4°F to 450°F) continuous service
- Cycle Life: >50,000 cycles under rated pressure conditions
| Model Variant | Port Size | Cv Factor | Torque Requirement |
|---|---|---|---|
| QBV-04DF | 1/4" | 5.2 | 30 Nm |
| QBV-06DF | 3/8" | 8.1 | 45 Nm |
| QBV-08DF | 1/2" | 14.0 | 65 Nm |
The valve's triple-sealed stem design incorporates primary PTFE seals, secondary spring-energized seals, and tertiary metal backup rings to ensure zero leakage even under extreme pressure cycling. Machined ball surfaces achieve Ra 0.2 μm surface finish for consistent sealing performance throughout the valve's operational life. Field-replaceable cartridge-style seat assemblies allow maintenance without removing the valve body from piping systems.
Operational Advantages:
- Corrosion Management: 316 SS construction resists pitting in chloride-rich environments including marine and chemical processing
- Installation Efficiency: Double ferrule connections enable 360° positional alignment during installation
- Fluid Compatibility: Compatible with hydraulic fluids, solvents, fuels, and gases including natural gas
- Safety Compliance: Meets ASME B16.34 pressure boundary requirements
Shanghai Quanbao's manufacturing capabilities in Shanghai include CNC machining centers with 5μm positional accuracy and automated cleaning systems that ensure particulate-free components. Our production process includes 100% pressure testing at 1.5x rated pressure and helium leak testing for critical applications. With over 15 years of experience supplying fluid control components to global industries, we maintain strict traceability from raw material to finished product.
This ball valve is engineered to reduce total cost of ownership through extended service intervals and simplified maintenance. The double ferrule connection system eliminates the need for thread sealants and prevents tubing distortion common in single-ferrule designs. For applications requiring customized configurations, optional features include lockable handles, position indicators, and NACE-compliant materials.
Frequently Asked Questions:
Q: Can this valve handle steam applications?
A: Yes, when equipped with high-temperature seals (optional), it can manage saturated steam up to 232°C at corresponding pressures.
Q: What tubing materials are compatible with the double ferrule connections?
A: The connections work with 316SS, carbon steel, and alloy tubing meeting ASTM A269 specifications.
Q: Is backflow prevention integrated?
A: This is a standard ball valve without check functionality. For backflow prevention, consider adding a separate check valve.
Q: What is the lead time for custom configurations?
A: Standard items ship within 3 days. Customized valves typically require 2–3 weeks depending on specifications.
Q: Are wrench flats provided for installation?
A: Yes, hexagonal wrench flats are machined on the valve body for secure installation.
Q: What maintenance is required?
A: Periodic stem lubrication is recommended. Seat assemblies can be replaced without special tools.
