1. A globe valve uses valve stem pressure to make the sealing surface of the disc and sealing surface of valve seat fit tightly to cut off the medium. It's a forced seal valve.
2. Flow direction of the medium in globe valve contains "low in and high out" and "high in and low out". The medium is allowed to flow in only one direction. The valve shall be installed in right direction.
3. Globe valve has structure of straight-through type, direct flow type and right angle type.
4. When a globe valve is open, and the opening height of the disc is up to 25%-30% of nominal diameter of the globe valve, the flow reaches the maximum, which shows that the globe valve is in a fully open position.
