Shanghai Quanbao Electronic Materials Technology Co., Ltd., a trusted manufacturer based in Shanghai, China, proudly presents the Double Ferrule Ball Valve with Locking Lever. Engineered for demanding industrial environments, this valve ensures secure and reliable flow control for both gas and liquid systems. Its innovative design combines leak-proof integrity with operational safety, making it ideal for critical applications where precision and tamper-resistance are paramount. With rigorous quality control from our Shanghai facility, we deliver robust performance that minimizes downtime and maintenance costs.
This valve features a high-strength stainless steel body and chemically resistant PTFE seals, providing exceptional durability against corrosion and wear. The double ferrule compression fitting system guarantees zero-leak connections without requiring specialized tools, while the integrated locking lever prevents accidental or unauthorized actuation. Below are key technical specifications and advantages:
- Leak-Proof Security: Dual ferrule design compresses tubing twice for superior sealing under high-pressure conditions.
- Tamper-Resistant Operation: Locking lever mechanism requires a key or tool for adjustment, ensuring process integrity.
- Broad Compatibility: Compatible with stainless steel, copper, and nylon tubing across multiple industries.
- Low Torque Handling: Smooth 90-degree operation reduces operator fatigue during frequent cycling.
| Model Size | Max Pressure (PSI) | Temperature Range | Flow Coefficient (Cv) |
|---|---|---|---|
| 1/4" | 1000 | -20°F to 300°F | 1.8 |
| 3/8" | 800 | -20°F to 300°F | 3.2 |
| 1/2" | 750 | -20°F to 300°F | 5.0 |
Industries such as chemical processing, semiconductor manufacturing, and oil/gas rely on this valve for its consistent performance in hazardous environments. The full-port ball design minimizes pressure drop, while the blowout-proof stem enhances operator safety. Custom configurations including specific tube materials or locking mechanisms are available upon request to meet unique operational needs.
