New Product Development

Thermal Actuator & Valve Design - Engineer Using SolidWorks with MD Valve

Thermal actuator design and manufacturing on-site allow us the unique ability to customize open and closing temperatures into precise ranges for your applications’ needs. Our engineers can customize the material, valve size, flow rates, number of inlets/outlets, and other optional features such as overrides.

Our product development services include SolidWorks 3D CAD design and Solidworks flow simulations.

Reverse Engineering

We offer mechanical and electrical reverse engineering for obsolete or single-source parts. This service can be stand-alone or combined with additional new product development and testing.


Thermal Actuator Design and Manufacturing Prototyping

Our product development center is housed in the same building as our manufacturing facility, which allows for prototyping and small-batch runs for your custom designs. Prototyping is often multi-staged, with R&D or field testing in between each batch.

R&D Testing

All new product development is supported by our on-site research and development testing equipment. We utilize a model shop and test stands for pressure, temperature, and flow measurements with wireless DAQ capabilities to ensure correct intended functionality.

Project Management

Our exemplary project management and customer service are at the heart of all our engineering projects. We support you through every step – planning, scheduling, resource forecasting, and technical support – to guarantee a product that will exceed expectations.


Manufacturing Capabilities

Components used in Aerospace & Defense applications are held to strict standards and often require component traceability and serialization. ThermOmegaTech® is an AS9100D certified production facility with state-of-the-art CNC turning and milling centers controlled by our skilled staff with the help of sophisticated digital systems.

We manufacture valves from precision machined parts in stainless steel, aluminum, titanium, Monel, Inconel, Hastelloy, and other exotic metals to meet the high stress and low weight material requirements of many A&D applications. 

Our team maintains a high standard of quality control throughout every step of the production process, offering full part and lot traceability on components for your project.
