  • Globe valve uses valve stem pressure to make the sealing face of valve clack and sealing face of valve seat fit tightly to cut off medium. It's a forced seal valve.
  • Flow direction of medium in globe valve includes "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.
  • Globe valve has structure of straight-through type, direct flow type and right angle type.
  • When globe valve is open, and the opening height of valve clack is up to 25% ~ 30% of nominal diameter of the globe valve, the flow reaches the maximum which show that the valve reaches the fully open position.
