DESEINOR Dry Disconnect Coupling is a professional hose connection device, designed to achieve **automatic double-sided sealing** upon disconnection between hoses and fixed pipeline terminals. It is mainly used in scenarios that demand rapid, leak-free connection and disconnection of fluid or air pipelines, which can minimize fluid loss and contamination risks to the greatest extent. DESEINOR dry disconnect couplings are widely applied in the filling systems of chemical, petroleum, LPG and other industries.
This device effectively improves operational efficiency, and reduces environmental impact by mitigating the risks of spillage and contamination.### Parameter Introduction of DESEINOR Dry Disconnect Coupling
#### Dimension Specifications
Available in different nominal diameter specifications such as 2 inches, 2.5 inches, 3 inches, 4 inches, 6 inches, and 8 inches, it is suitable for various pipeline systems.
#### Material
- **Main Body**: Mostly made of 316 stainless steel (for example, some products use ASTM A 351 Grade CF8M 316 stainless steel), which has good corrosion resistance. Options like aluminum alloy, brass, Hastelloy, titanium, PVDF, and PEEK are also available (to adapt to special working conditions).
- **Sealing Material**: Includes PTFE (Polytetrafluoroethylene), FKM (Fluororubber, such as Viton type), NBR (Nitrile - butadiene Rubber), EPDM (Ethylene - Propylene - Diene Monomer), FFKM (Perfluoroelastomer), etc., to adapt to different fluid media and temperature environments.
#### Performance Parameters
- **Working Pressure**: The maximum working pressure is usually between 10 - 25 bar (for some products, like the 1 - inch specification, it can reach 210 psi, approximately 14.3 bar; there are also standards like 100 psi, approximately 6.9 bar), and it is designed with a 5 - fold safety factor.
- **Working Temperature Range**: Different sealing materials are suitable for different temperatures. For example, when matched with PTFE sealing, the common working temperature is - 7℃ to + 110℃ (that is, 20°F to 230°F); some FKM seals can adapt to higher temperatures, such as around 300°F (approximately 149℃).
- **Vacuum Performance**: Tested, some products can withstand a vacuum degree of 20 inches (711mm) Hg in all positions without leakage.
- **Flow Rate**: Different sizes correspond to different flow rates. For example, the 1 - inch (DN25) specification can reach 250 L/min, the 2 - inch (DN50) can reach 900 L/min, the 3 - inch (DN80) can reach 2800 L/min, the 4 - inch (DN100) can reach 7000 L/min, the 6 - inch (DN150) can reach 14000 L/min, and the 8 - inch (DN200) can reach 23000 L/min (specifically depending on the configuration).
- **Coupling Cycle Times**: Some high - quality products can exceed 500,000 coupling cycles, ensuring long - term durability.
#### Connection and Operation Parameters
- **Connection Method**: Provides threaded (such as BSP, NPT and other standard threads, with forms like internal thread FNPT, external thread) and flange (such as ANSI, EN, TW, TTMA, JIS and other standard flanges) connections, suitable for the installation of hose units and tank units.
- **Operation Characteristics**: Most are controlled by a single handle, which can realize the integrated actions of locking, sealing, and disconnecting; it has a mechanical interlock mechanism to prevent accidental opening and ensure operation safety.
