Working Principle Of Electric Stop Valve

The electric stop valve, also called the electric gate valve, is the most widely used valve. It is different from the electric ball valve. The reason why it is so popular is that the friction between the sealing surfaces during opening and closing is small, it is relatively durable, the opening height is not large, it is easy to manufacture, and it is convenient to maintain. It is not only suitable for medium and low pressure, but also for high pressure. The closing principle of the electric stop valve is to rely on the electric thrust to rotate the valve stem so that the valve disc sealing surface and the valve seat sealing surface fit tightly to prevent the flow of the medium. The electric stop valve only allows the medium to flow in one direction, and it has directionality during installation. The structural length of the stop valve is greater than that of the gate valve, and the fluid resistance is large. During long-term operation, the sealing reliability is not strong.
