Electric Globe Valve
Introduction:
The electric globe valve is the most widely used valve. It is not only suitable for medium and low pressure, but also suitable for high pressure.
The closing principle of the electric globe valve is to rely on the electric thrust to rotate the valve rod, so that the sealing surface of the disc and the sealing surface of the valve seat fit closely to prevent the flow of medium. The electric globe valve only allows the medium to flow in one direction, and it is directional when installed. The structural length of the stop valve is longer than that of the gate valve, and at the same time, the fluid resistance is large, and the sealing reliability is not strong during long-term operation.
Features:
The electric globe valve is a valve whose disc moves along the center line of the valve seat. The globe valve is mainly used for cutting off in the pipeline.
1) During the opening and closing process, the friction force of the sealing surface is smaller than that of the gate valve, and it is wear-resistant.
2) The opening height is small.
3) Usually there is only one pair of sealing surfaces, the manufacturing process is good, and it is easy to maintain. Globe valves are commonly used, but due to the large opening and closing torque and long structural length, the general nominal diameter is limited to DN≤250mm.
