TLX introduces new modular valve products for EV thermal management

US-based solenoid and valve system manufacturer TLX Technologies is introducing the first two components in its new family of modular 4-way and 3-way switching valves, designed to give OEM and system design teams thermal management controls that suit multiple vehicle platforms.

The high-flow valves deliver low cross-flow leakage, reducing the challenge for design teams to develop a thermal management system with the desired thermal efficiency and flow control characteristics.

The valves do not require constant power to maintain a commanded position and their efficient fluid flow path minimizes pressure drop, allowing the vehicle’s coolant pump to support the system’s fluid management requirements with less power, the company said. This contributes to reducing the vehicle’s overall energy consumption.

TLX’s new modular valve family can be used for vehicle platforms that have different communication protocol, operating voltage, and port size requirements. The valves support both 12 and 24 VDC operation and nearly any port size up to 25.4 mm without any changes to the valve body, flow paths, or drive system. They can use either PWM or LIN communication protocols.
