The 400988932 check valve produced by FE Petro was developed to accommodate a variety of electronic and mechanical equipment used in Line Leak Detection today. Electronic Line Leak Detectors manufactured by several companies require that the line pressure relieve to a certain pressure (in PSI) to conduct a proper leak test. This relief pressure varies depending on the requirements of the electronic equipment.
Key Features
