Designing a 3″ Solution to a Big A&D Challenge


Designed with the most advanced and reliable thermal actuator technology available today, ThermOmegaTech® valves are compact, reliable, and fast acting. Offered in a variety of shapes, sizes, and materials, they are the invaluable cornerstone of any A&D project involving thermal management of fluids.

An established leader in self-actuating thermostatic technology, ThermOmegaTech® line of products is making waves in the aerospace and defense (A&D) industry. Even for unusual or extreme applications, our experienced team of multi-disciplinary engineers can devise a unique and practical solution to meet your project’s challenges.

A system supplier to the U.S. Department of Defense recently came to us with a need for a product that would act as a thermal bypass valve on a military vehicle’s hydraulic manifold, bypassing cold hydraulic fluid to reduce the load on the system and allow it to come up to operating temperature more quickly. Some of the challenges for this application included high operating pressure, specific flow and pressure drop requirements, and size restrictions to fit into the existing manifold.

ThermOmegaTech® engineers worked one-on-one with the customer, overcoming roadblocks to design a solution that satisfied all the project’s requirements.

The custom modifications made to a stock thermal bypass valve for this project included increasing the size of the actuator to handle higher loads, increased flow rate, using a stronger return spring to accommodate operating at high pressure, and implementing an actuator with a custom temperature set-point, all made to fit into the available 0.75″ x 3.0″ space.

After successfully testing prototypes, the customer implemented the custom thermal bypass valve into hundreds of military vehicles.

Throughout the project, our engineers maintained constant contact with the customer, considering several iterations and providing prototypes before proceeding to production, to ensure a product that functioned optimally under the project’s unique conditions. The customer valued ThermOmegaTech® constant communication, quick turnaround time, and commitment to finding the optimal design, ultimately awarding the project to ThermOmegaTech®.
