The CQA41F-25 Series is a specialized, high-safety ball valve engineered specifically for the loading and unloading systems of liquefied gas tankers and storage tanks. It serves as an essential safety component, typically paired with emergency shut-off valves to provide reliable flow control, isolation, and diversion of hazardous media during transport and transfer operations.
Featuring a one-piece body construction and a floating seat design, this valve is optimized to prevent external leakage and ensure long-term sealing reliability in demanding mobile environments.
- Leak-Proof One-Piece Body: The unified body design eliminates potential external leak paths, ensuring maximum containment of hazardous fluids.
- Adjustable Floating Seat: The advanced seat structure allows for the adjustment of pre-tightening forces, ensuring a bubble-tight seal even after extensive use.
- Quick-Connect Interface: The outlet is equipped with a professional quick-coupling connector, allowing for rapid, secure, and leak-free hose connections.
- Extreme Temperature Resistance: Designed to operate reliably in harsh environments, with a working temperature range of -40 °C to +80°C.
- Corrosion-Resistant Materials: Available in high-grade Stainless Steel (CF8/CF8M) to handle aggressive chemical media and prevent rust in outdoor conditions.
