Operating Principle
The plug contains an internal poppet-style valve that remains sealed until it mates with the corresponding ISO‑A socket. When engaged, locking balls secure the plug and open the valve, allowing hydraulic fluid to flow. On disconnection, the valve closes instantly to prevent fluid loss or contamination. The threaded interface ensures a stable, vibration-resistant connection to eliminate accidental separation. Together, this design enables fast, clean, tool‑free connection and disconnection in industrial and mobile hydraulic applications.
