Smartflow Dry Break Coupling for Fluid Transfer – CEJN

The Smartflow dry break coupling was designed to ensure safe, efficient and sustainable fluid transfer in aggressive, highly critical environments. Connection and disconnection are performed without spills. The design reduces the number of parts and eliminates the need for additional valves, saving time and reducing operating costs. The line meets the demands of Oil & Gas, petrochemical, Food & Beverage, road and rail transport, marine operations and aviation. Typical applications include AdBlue distribution, road and rail tankers, offshore operations, bunkering and IBC filling.

Key Technical Data

• Maximum working pressure: 25 bar (362 PSI)
• Safety factor: 5:1
• Materials: Aluminum, stainless steel
• Media: Industrial fluids, AdBlue, and other compatible media
• Available sizes: 1”, 2”, 2.5”, 3”, 4”
• Standards: TEAM SPEC, STANAG 3756
• Seals: Multiple O-ring options, including FDA-approved compounds

Interoperability and Cost Savings

Thanks to the 5:1 safety factor, the Smartflow family allows customers to choose aluminum units as a lighter and more cost-effective alternative to stainless steel versions in higher-pressure applications.

Smartflow couplings are interchangeable with products from other manufacturers according to TEAM SPEC and STANAG 3756 standards, simplifying fleet retrofit and standardization processes.

Operation and Ergonomics

The couplings are available in sizes ranging from 1” to 4”. Smaller sizes can be operated manually, while larger sizes require higher torque for connection and disconnection.

Single or double handles facilitate operation in high-force applications.

The actuation system uses a trigger mechanism activated when connecting the hose side (female coupling) to the tank side (male adapter). When rotated clockwise, the coupling locks and releases the flow. Counterclockwise rotation unlocks the coupling and stops the flow with spill-free operation.

This operating method reduces contamination risks and minimizes operator exposure to fluids.

Key Features and Benefits

• Efficiency and Productivity: The elimination of spills and waste, combined with reduced downtime, improves process efficiency and increases productivity.
• Health and Safety: The elimination of fluid spills, including hazardous fluids, reduces risks to operator health and improves compliance with safety standards.
• Cost Reduction: Reduced product waste and lower downtime result in significant operational savings.
• Environmental Sustainability: Spill-free systems prevent environmental contamination and help companies achieve sustainability goals.
• Seal Versatility: Multiple O-ring options, including FDA-certified compounds, allow use in industries requiring high hygiene standards, such as food and beverage.
• Robustness and Reliability: Designed for harsh environments, the system is rated for 25 bar with a 5:1 safety factor, ensuring consistent performance.
