10000 psi check valve is a kind of pipeline valve. Its structure and usage method are between check valve and stop valve. It can not only prevent the backflow of fluid, but also control the flow of fluid. It includes two functions of a check valve and a globe valve. When the pressure is on both sides of the valve, it acts like a check valve to prevent the reverse flow of fluid; when the valve needs to be closed, it acts like a globe valve and can Stop the flow of the pipeline completely. The structure of the stop check valve is divided into two types: axial type and horizontal type. The axial type valve usually adopts a diaphragm structure, and the horizontal type valve usually adopts a gate structure.
