Can the Quick-connect coupling socket, DN7.2 Eurostandard with valve, with hose socket, 25 bar, SWING SC be connected or disconnected under pressure and what are the pressure limits?

Quick-connect coupling socket, DN7.2 Eurostandard with valve, with hose socket, 25 bar, SWING SC can be connected and disconnected under pressure with limits: working pressure 25 bar; connection and disconnection under pressure permitted up to 15 bar. The design allows the plug to be pressed into the socket when the plug entry is tilted ~90Â° (flow cut off), enabling coupling under pressure; to open flow the assembly is tilted to straight and locked. Venting through a hole during ~90Â° movement prevents recoil on disconnection. Operating temperature with NBR seals: -20Â°C to +100Â°C.

Q: How does the tilt mechanism of the Quick-connect coupling socket, DN7.2 Eurostandard with valve, with hose socket, 25 bar, SWING SC enable safe venting during disconnection?

The Quick-connect coupling socket, DN7.2 Eurostandard with valve, with hose socket, 25 bar, SWING SC enables safe venting during disconnection by incorporating a tilting mechanism that vents the line before full separation. When the plug is pressed into the socket at ~90Â° to the body, flow is cut off so connection can be made under pressure. For disconnection, the movable part and plug are tilted back ~90Â°; this change in position opens a vent hole in the socket body that releases residual pressure safely, preventing a recoil effect. The flow is only reopened when the parts are returned to the straight, locked position in the socketâs grooves. Working pressure: 25 bar (15 bar for connect/disconnect under pressure).

Additional information

Material	CS – steel (cast iron)

Tilted quick coupling socket with valve and hose end, for full flow, intended for compressed air, gases, liquids of low and medium viscosity. Compatible with most popular plug systems, plug profile compliant with the popular EURO DN7.2 standard. Connection occurs by pressing the plug into the socket when its entry is in a position of approximately 90° relative to the rest of the body. At this moment, the flow of the medium is cut off, and the operation can be performed even when the rest of the installation is under pressure. To open the flow, the movable part of the socket along with the plug must be tilted to a straight position, and the ring on the socket body must be locked in special grooves. The venting of the quick coupling occurs through a hole in the socket body by changing the position of the plug by approximately 90°. This helps avoid the recoil effect during disconnection. Working pressure: 25 bar (15 bar for connecting and disconnecting under pressure). Material: nickel-plated steel / aluminum. Operating temperature: from -20°C to +100°C (NBR sealing).
