Can the Foldable Quick Coupling Socket DN7.2 Eurostandard, Valve, Threaded, 25 bar, SWING SC be connected or disconnected under pressure without leakage?

Yes. The Foldable Quick Coupling Socket DN7.2 Eurostandard, Valve, Threaded, 25 bar, SWING SC is designed to be connected and disconnected under system pressure safely and without leakage. Its 90° tilted connection allows plug insertion under pressure while the internal valve automatically shuts off the medium. Once the socket and plug are tilted to a straight position the flow opens and the locking ring secures the joint. For disconnection, the coupling vents through a built-in outlet in the socket body to avoid recoil and prevent leakage, complying with ISO 4414 and EN 983. Note: maximum working pressure is 25 bar, but connection/disconnection under pressure is limited to 15 bar.

How does the Foldable Quick Coupling Socket DN7.2 Eurostandard, Valve, Threaded, 25 bar, SWING SC prevent recoil and ensure operator safety during disconnection under pressure?

The Foldable Quick Coupling Socket DN7.2 Eurostandard, Valve, Threaded, 25 bar, SWING SC prevents recoil and ensures operator safety during disconnection under pressure through several integrated features: - Tilt-to-open valve: The 90° (foldable) design keeps the internal valve closed while the plug is inserted under pressure. Flow only starts when the socket and plug are aligned straight, preventing sudden bursts during mating or unmating. - Built‑in venting outlet: On disconnection the socket vents residual pressure through a dedicated outlet in the socket body, safely releasing trapped medium before full separation. This controlled depressurisation eliminates recoil. - Automatic shut‑off and locking ring: The valve automatically shuts off the medium when tilted; the locking ring engages into dedicated grooves when straight, securing the connection during use and preventing accidental release under pressure. - Compliance and ratings: Designed to operate up to 25 bar (with safe pressurised connection/disconnection at 15 bar) and built to ISO 4414/EN 983 principles, the coupling’s materials (nickel‑plated steel/aluminium and NBR seals) ensure reliable sealing and structural integrity that protect operators during routine and pressurised operations. Together these features provide controlled venting, positive shut‑off and secure locking to prevent recoil and protect the operator during disconnection under pressure.

Additional information

Material	CS – steel (cast iron)

The tilted quick coupling socket with full flow valve is a reliable and versatile solution for safe and efficient transfer of compressed air, gases, and low to medium viscosity liquids. Designed to fit the widely used EURO DN7.2 plug profile, it ensures broad compatibility with popular plug-in systems. The innovative 90° connection mechanism allows the plug to be inserted even under system pressure, with automatic shut-off of the medium flow for maximum safety. To activate the flow, the socket and plug are tilted into a straight position, and the locking ring secures the connection in dedicated grooves, guaranteeing stability during operation. Disconnection is equally safe, as venting occurs through a built-in outlet in the socket body, eliminating recoil and protecting the operator in compliance with ISO 4414 and EN 983 standards. Available with both internal and external BSP threads, the coupling offers flexibility for diverse installation requirements. With a working pressure of up to 25 bar (15 bar during pressurized connection and disconnection), durable nickel-plated steel and aluminum construction, and reliable NBR sealing, it delivers long-lasting performance in demanding environments. Operating effectively within a temperature range of -20°C to +100°C, this coupling is the ideal choice for industries seeking efficiency, safety, and durability in fluid and air handling systems.
