Pressure and heat analysis

For High-temperature systems

January 27, 2019

A part of our research is focused on understanding the effects of the extreme pressures and temperatures the valve has to endure and use that to improve our valve design. The main challenges facing the valve development remain scaling, and corrosion but thermal expansion also hinders flow from the well. By redesigning the system and using unique materials, we strive to solve these problems and deliver a superior product to our customers.
