ESP Valve was founded on July 4, 1987 by Mark Leto, in Gonzales, LA. His passion for control valves and focus on customer service is what has helped ESP grow to what it is today. Nearly four decades later, ESP is still setting the standard for control valve remanufacturing! Mark’s passion and dedication has now been passed down to his son, Jay, who is now the second generation owner. Since taking over the business jay has expanded operations to becoming a fully VR certified PSV testing facility. The company is now in the process of building a brand new state-of-the-art headquarters facility located in Gonzales, LA.
