SUFA high pressure hydrogenation stop check valve is suitable for refining hydrogenation unit, including residue oil hydrogenation, wax oil hydrogenation, gasoline and diesel hydrogenation, lubricating oil hydrogenation, aromatics hydrogenation, etc., also applicable to other similar conditions. Integrating the globe valves and check valves together reduces the number of valves and pipe connections in the system, reducing the complexity and cost of the system. It can both prevent the medium backflow and realize the cut-off function.
