Hygienic industrial high-pressure valves, also known as shut-off valves, are the most widely used valves. The reason why they are popular is that the friction between the sealing surfaces is small, durable, the opening height is not high, easy to manufacture, easy to maintain, not only suitable for low and medium pressure, but also suitable for high pressure. The closing principle of globe valve is to make the disc sealing surface and the seat sealing surface closely adhere to prevent the flow of media by relying on the pressure of the valve bar. Cut-off valves allow only one-way flow of media and are directional when installed. The structure length of the globe valve is longer than that of the gate valve. At the same time, the fluid resistance is large, and the sealing reliability is not strong when the globe valve runs for a long time.
