Globe valve advantages

(1) the structure of the globe valve is simpler than the gate valve, and the manufacture and maintenance are more convenient.
(2) the sealing surface is not easy to wear and scratch, good sealing, open and close between the valve disc and the valve body sealing surface without relative sliding, so wear and scratch are not serious, good sealing performance, long service life.
(3) when opening and closing, the disc stroke is small, so the height of the globe valve is smaller than the gate valve, but the length of the structure is longer than the gate valve.
(4) the opening and closing torque is large, the opening and closing stranding is laborious, the opening and closing time is principal.
(5) the fluid resistance is large, because the medium channel in the valve body is tortuous, the fluid resistance is large and the power consumption is large.
(6) when the nominal pressure Pn in the direction of medium flow is less than or equal to 16Mpa, it is generally downstream, and the medium flows from the lower direction of the valve disc; Nominal pressure Pn ≥ 20Mpa, generally use countercurrent, medium flow from the direction of the disc. To increase the sealing capacity. When in use, the cut-off valve medium can only flow in one direction and cannot change the direction of flow.
(7) when fully open, the disc is often eroded.
The axis of the valve stem of the globe valve is perpendicular to the sealing surface of the valve seat. Stem open/close stroke is relatively short and has very reliable cut-off action, making this valve suitable for medium cut-off or regulating and throttling use.
