As the world leader in self-actuated temperature control solutions, ThermOmegaTech® prides itself on the high-quality manufacturing process, problem-solving approach and innovative engineering techniques used to build and manufacture self-actuated valves and specialty products that leverage proven technological methods.

At the heart of each of our products is a phase change wax that expands and contracts at an accurate and repeatable rate. Historically, the idea was that this wax could be used to mechanically power thermal actuators, thus bringing about a new technology to enhance efficiency and reliability of temperature control. The phase change properties are so precise that they are used as primary reference standards by ASTM for instrument calibration.

Temperature Control Valves and Actuators

ThermOmegaTech® has incorporated this technology into the Thermoloid® material that makes all of our valves work. When the Thermoloid® material is heated above the melting point, it expands and pushes on the diaphragm, which in turn pushes on a piston. This piston acts as a valve stem, opening or closing a valve. As the Thermoloid® material cools, it returns to its original state and a spring inside returns the piston and diaphragm to its cold position.
