| Payment Method: | L/C,D/A |
The TLOK-S series is a patented dual-interlock quick coupling specially engineered for liquid cooling main loop pipelines, combining Storz coupling structure and built-in ball valve as one integrated unit. Equipped with exclusive internal interlocking mechanism, this coupling realizes fast connection & disconnection, multi-layer error-proof protection, and ultra-low residual fluid spillage during separation. It is widely adopted in large-scale data center liquid cooling systems, industrial cooling circuits and fluid transfer pipelines, delivering maximum operation safety and system efficiency for global cooling projects.
Flow & Pressure Drop Curve of TLOK-S Coupling
- All-in-one coupling & ball valve with reliable dual-interlock system
The ball valve and quick connector are perfectly integrated as a single assembly, supporting instant connect and disconnect. The dual interlock structure eliminates misoperation risks fundamentally.
- Genderless fully interchangeable design
No male/female distinction for universal matching. After full connection, two handles align in a straight horizontal line on the same plane, allowing users to visually confirm successful docking at a glance. It only requires tiny space for comfortable one-hand operation.
- Interlocked linkage internal structure for top safety
Two coupling halves are mechanically interlocked: the built-in ball valve can only be opened when the two parts are fully locked together. Before disconnection, both side valves must be fully shut off automatically, effectively preventing coolant leakage and accidental fluid spraying.
- Handle lock button against unintended operation
Each handle is fitted with a dedicated locking push button to avoid accidental opening/closing during transportation or pipeline vibration.
- Color-coded rubber impact-resistant head sleeve
The rubber protective sleeve on the coupling head prevents collision damage during installation and maintenance. Multiple color options are available to mark different coolant media and avoid cross-connection mistakes.
- 360° swivel end for flexible installation
The rear connection end supports thread, chuck or tailpipe options with full 360-degree rotation function. Operators can freely adjust installation angles to reduce hose twisting and extend hose service life.
- Customizable large bore sizes for high flow
Standard sizes cover 1", 2", 3", 4". Custom large bore versions including DN50 (2-inch) are available to satisfy high-flow liquid cooling main loop demands.
- Customizable body & sealing materials
Stainless steel body and EPDM seal are standard; alternative body and seal materials can be customized to match special fluid, temperature and pressure working conditions.
- Universal interchangeability
Mechanically compatible with most mainstream brands of Storz liquid cooling couplings on the market, easy for project replacement and retrofitting.
- Optional actuator for remote automatic control
External actuators can be mounted on the valve handles to realize remote on-off control for automated liquid cooling systems.
