Ideal for circuits with residual pressure; allows connection without loss of operating fluid.
The "APM" male flat face coupling was developed for the purpose of manual connection in circuits with residual pressure. This coupling employs a triple valve system (double internal residual pressure release valve + flat face valve). By using this system, it is possible to connect in circuits with residual pressure without losing hydraulic fluid. This system makes the "APM" coupling an ideal product for circuits with residual pressure. 【Features】 ○ Easy to clean, effectively reducing contamination intrusion into the system ○ No loss due to hydraulic fluid leakage during connection and disconnection, reducing environmental impact ○ Minimizes air entrapment during connection and disconnection, aiding optimal system operation ○ Allows manual connection even with high residual pressure due to the internal residual pressure release valve system ○ Modular structure enables diverse specifications for ports ○ Strong against peak pressure ○ Compact appearance ○ Safe and simple to use ● For more details, please contact us or download the catalog.
