Product Description

The interlocking valve features a dual-locking mechanism that requires complete connection before the valve can open, and full closure before disconnection is possible. This prevents accidental coolant leakage and equipment damage during live maintenance. Strong bending moment resistance handles large hose loads in high-flow applications. Supports online hot-swap — new modules connect without system shutdown. Reserved ball valve interface for flexible system expansion.
