Features

(1) The structure is simpler than gate valve, and it is easier to manufacture and maintain.

(2)The sealing surface is not easy to wear and abrasion, good sealing, no relative sliding between the valve flap and the sealing surface of the valve body when opening and closing, so the wear and abrasion are not serious, good sealing performance, long service life.

(3)When opening and closing, the flap 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) opening and closing torque, opening and closing more laborious, opening and closing time principal.

(5) Fluid resistance, because the valve body media channel is more zigzag, fluid resistance, power consumption.

(6) Medium flow direction

Nominal pressure PN ≤ 16MPa, generally used downstream, the media from the valve flap upward direction; nominal pressure PN ≥ 20MPa, generally used countercurrent, the media from the valve flap upward downward flow. To increase the sealing energy. When used, the cut-off valve medium can only flow in one direction, can not change the flow direction.

(7) full open valve flap is often subject to erosion.
