Cold plates at the CPU and GPU leave no margin for error. TLX valves meter coolant per rack or per blade with high-speed response and leak-resistant designs, delivering targeted flow that prevents hot spots without wasting pump energy.
Cold plate loops balance flow across dozens of parallel paths. TLX designs proportional and multi-port valves with high flow and low pressure drop, so the coolant pump works less and PUE (power usage effectiveness) improves.
Closed loops manage heat from multiple sources on one coolant budget. TLX discrete proportional valves reposition on a brief pulse and hold with zero power draw, directing flow where the heat is without adding to the energy bill.
Dielectric fluids demand compatibility most valves were never designed for. TLX engineers valve materials and seals around the specific immersion fluid, single-phase or two-phase, balancing chemical resistance with flow performance.
Facility-scale evaporative systems still come down to valves metering water reliably for years. TLX designs around the duty cycle, water quality, and service life the installation requires.
A leak near live hardware is measured in seconds. TLX integrates sensor feedback and supervised valve designs that confirm their own state and isolate a loop instantly when something goes wrong.
Dense electronics and lithium battery systems make suppression a design requirement, not an afterthought. TLX actuates fire suppression systems across agent types and pressures, with supervised valves engineered for mission-critical environments.
TLX designs custom valves tailored for your cooling system. Functionality, materials, and design are carefully balanced to meet your objectives, including:
Advanced valve technologies, including latching designs that hold position with zero power draw, to maximize energy efficiency and improve data center PUE.
High flow and low pressure drop across every valve position, maximizing the coolant pump's efficiency and further reducing energy costs system-wide.
High-speed valves with targeted coolant delivery, responding to shifting thermal loads in real time to prevent hot spots before they threaten hardware.
Material grade selections matched to your coolant chemistry, preventing erosion of internal valve components and flow paths while protecting coolant fluid purity.
Leak-resistant designs validated through 100% end-of-line testing, engineered for a long, low-maintenance service life in systems that never get to stop running.
Custom designed to meet tight space constraints, with inlet, outlet, and connector options tailored to fit any liquid cooling system architecture.
TLX designs and develops custom solenoids and valves for the latest data center and server cooling applications, expertly engineered to your exact needs.
TLX engineers work alongside your team to design and produce custom solenoid valves and valve systems, engineered around your flow rates, fluid, footprint, and power budget rather than adapted from a catalog. From first conversations through production, your project gets direct access to our technical and engineering resources. One team, from start to finish.

Low power consumption and predictable, repeatable flow rates are combined in one valve system.
A bistable latching solenoid was designed to lock and unlock individual servers in the rack.
