Our series of engineered valve designs are integral to the refining industry. They play a critical role in managing media flow and isolation during the production phase of fuels, or ‘cracking’. They often endure abrasive process conditions and the high-temperature conditions of refineries. One of the main specialties we target is HPHT, or “High pressure, high temperature”, then add to that the high cycle rates and required reliability under plant safety requirements.

Our ability to combine exotic metallurgies with engineered designs has made Cornerstone a perfect fit for refining. We can utilize proven designs while adjusting for compatibility with unique plant demands. This capacity makes Cornerstone a memorable name in this industry.
