Mercer Valve was founded by Wesley Taylor with his Auto Seat Technology® patent for pressure relief valves. Auto Seat Technology® is incorporated into the valve design, allowing it to pop and reseat time and time again. Unlike the competition, the valve has a soft seat design with a fully guided disk and spring to help the valve have a longer life.

Mercer Valve has always strived to be safe minded and engineer driven. This is evident through the installation of a flow lab for increased quality testing and further research and development.
