Off-Highway Solenoids & Valves

Implements demand proportional control with the force to move hydraulic loads and the precision to place them. TLX proportional solenoid actuators power hydraulic valves across off-highway platforms, with peak-and-hold control that delivers high force without overheating the coil.

Off-highway drivetrains punish components. TLX designed a proportional valve that operates fully submerged in the hot transmission fluid of an all-terrain vehicle, meeting low-leakage requirements across a range of pressures, tested on a stand built to preheat the fluid to the customer's spec.

Logging vehicles, tractors, and electrified equipment all run thermal systems in dirt, vibration, and water. TLX coolant control valves are built for it, with IP67 submersible ratings, debris diverters protecting internal components, and coolant ranges from -40°C to 110°C.

Alternative fuels change everything about a valve. For natural gas vehicles, TLX achieved drastically low leakage with cold flexibility to -40°C using a fluorocarbon elastomer, applying finite element analysis and CFD to solve the fit and flow challenges natural gas creates.

As off-highway equipment electrifies, battery systems bring new demands for disconnects, thermal control, and fire prevention. TLX applies latching technology that holds state without power and proportional flow control that repositions on a brief pulse of power, protecting range and runtime.

Operator comfort is an engineering problem measured in hours behind the controls. TLX developed a continuous duty, three-way valve for a driver's seat air suspension system, the kind of precise pneumatic control that turns a long shift into a manageable one.
