Our 9100 Model 20 Series is state of the art when it comes to a soft seat and high flow rate design. It is an industry leader in pressure relief devices with a reputation for safety and reliability, low maintenance, and cost effectiveness. Our soft seat and fully guided disk design outlasts the competition and produces a valve that has consistent set pressures and a field proven tight lip seal. A tighter seal reduces leaks and limits product loss which leads to increased productivity and safety. The 9100 Model 20 Series valve is manufactured in accordance with the requirements of ASME Boiler and Pressure Vessel Code, Section XIII UV stamped applications for Air/Gas and Liquid service. This high pressure safety relief valve is designed for CNG and other high pressure applications from 3000 psi up to 8700 psi. When safety is on the line, this is a reliable valve you can trust.
