Operation Principle
This male coupling includes an internal poppet valve and retractable sleeve mechanism. When connected to the corresponding female socket, the sleeve retracts to open the valve and allow fluid to flow. Upon disconnection, the valve automatically closes to seal off flow and prevent leakage. The flat-face mating ensures a clean, drip-resistant disconnection even under residual pressure. The coupling enables fast, safe, and maintenance-friendly operation without tools.
