The globe valve is a tool that relies on the pressure of the valve stem to make the sealing surface of the valve flap closely fit the sealing surface of the valve seat to prevent the flow of media. It is a forced seal valve and is one of the most widely used valves.
According to the direction of the channel, the globe valve is divided into four types: straight-through globe valve, direct current globe valve, angle globe valve, plunger globe valve.
The structural length of the globe valve is greater than that of the gate valve, and at the same time, the fluid resistance is large. During long-term operation, the reliability of the seal is not strong.
