| 450B TYPE CUPLA |
■ Ball lock CUPLA that handles a normal working pressure of 450kg/cm2.
■ Sleeve stopper mechanism protects CUPLA from incidental disconnection caused by vibration or impact.
■ Metal touch valve system is ideal for ultra-high pressure hydranlic equipment. |
| |
|
| |
 |
| Features |
- Uitra-high pressure CUPLA with valve mechanisms in both socket and plug.
- Metal touch system is extremely durable.
- Prevening disconnection when in use, the stopper mechanism provides a high level of safety.

| Structure |
| When disconnected |
| Characteristically, there is an extremely slight leakage when CUPLA is disconnected due to the metal seal system but it is not a functional problem. |
|
| When When connected |
| Since there is no packing used in the valve, there is no packing wear even if flow velocity changes quickly. |

| Precaution |
- There is an extremely slight leakage when CUPLA is disconnected due to the metal touch system.
- Remove any dust adhering to the socket or plug.
- Do not use this CUPLA with hydraulic equipment where there is a significant amount of vibration or pulsative pressure.
