Operation Principle
This coupling features an internal spring‑loaded locking collar and poppet valve mechanism. When the matching male plug is inserted, the collar retracts and the valve opens, allowing hydraulic fluid to flow. Upon disconnection, the valve automatically closes to prevent spills and maintain system integrity. The flat‑face design ensures a clean, drip‑free separation, even under residual pressure. This tool‑free coupling enables fast, safe, and low‑maintenance operations in demanding hydraulic systems.
