| Structure : |
When
disconnected......
The socket and plug valves seal instantly, automatically shutting off fluid
flow to prevent leakage.
|
When connected
The socket and plug valves push together, opening to permit free flow of
fluid through coupling. An O-ring in the socket seals the plug surface
preventing any leakage. |
 |
 |
|
| |
Interchangeability :
Different size sockets and plugs are not interchangeable. |
 |
Precaution :
- Select packing material in accordance with the type
and temperature of fluid.
- Dust, foreign matter and flaws may cause leakage.
