Safety Interlock Ball Valve

Safety interlock ball valve with double-locking mechanism. For preventing accidental disconnection and coolant leakage during hot-swap maintenance in rack-level cooling.
* Support customization according to customer requirements
    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.
