The STCV swing check valve has a high integrity fully PFA encapsulated one piece disc with integral hinge pin and PFA lined body, designed for use in highly corrosive processes. It has a retained disc design overcoming installation problems associated with 2- piece designs where if the installer is not careful the disc can be dropped whilst locating between the mating flanges. The angled seat allows the valve to be installed in both horizontal and vertical applications. The non return valve has a simple operation and is ideal for use in controlling backflow of corrosive slurries as well as clean and clear applications. The size range up to 12” NB and its wafer pattern design makes it an ideal choice for larger bore piping processes, where fully flanged checked valves become very expensive.
