[Manufacturers] low quality cheap wholesale excellent quality cut-off valve

Brand: Southbridge Valve Model: J41H Connection: Flange nominal diameter: 100mm Material: Carbon Steel Scope: aquatic Model: J41H Temperature: 200 Pressure range: 16Mpa Applicable media: Steam Seal type: Hard Seal Standard: GB Shape: Large flow direction: commutation drive modes: manual parts and accessories: Ball Purpose: Relief Pressure environment: atmospheric temperature: vacuum type (channel position): straight low cut-off valve is closed parts (valve) along the center line of the valve seat to move. According to this form of valve movement, changes in the seat through the mouth is proportional to the valve stroke. As such the valve stem to open or close the relatively short trip, but also has a very reliable cutting function, but also due to travel proportional to changes in the valve seat and the valve port valve is very suitable for flow regulation. Therefore, this type of valve is suitable for cutting or regulation and throttle use. 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, long service life; (3) when opening and closing the valve flap a small stroke, which is 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 a long time; the big (5) fluid resistance, due to the valve body media path more tortuous, large fluid resistance, power consumption; (6) Nominal PN≤16MPa medium flow direction, the general use of cis stream media from the valve upstream direction; 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) the fully open valve is often affected by erosion.
