Technical parameters: globe valve Product Description: Features: (1) simple structure than the gate, manufacturing and maintenance are more convenient. (2) sealing surface easy to wear and abrasion, sealing, and no relative sliding between the valve and valve sealing surface when opening and closing, and thus wear and scratches are not serious, good sealing performance and long service life. (3) When opening and closing, the valve stroke is small, and therefore smaller than the height of the valve shut-off valves, but the structure is longer than the length of the gate. (4) opening and closing torque, relatively effortless opening and closing, opening and closing time principal. (5) fluid resistance, due to the valve body media path more tortuous, large fluid resistance, power consumption. (6) Nominal medium flow direction PN≤16MPa, generally used downstream, upstream from the media under the direction of the valve; when nominal PN≥20MPa, generally countercurrent, media orientation downstream from the valve. To increase the seal performance. When used, the cut-off valve medium can only flow in one direction, you can not change the direction of flow. (7) when fully open valve is often affected by erosion. 7. Other technical specifications by "a number of technical provisions oxygen tube steel enterprise network."
