    DIN Flanged Cast Steel Bellows Seal Globe Valve
     
    Introduction
    The DIN flange cast steel bellows seal globe valve is named for its spherical body shape with two halves of the body being separated by an internal baffle. Featured by long service life and good sealing performance, bellows sealed globe valves are broadly applied in mining, petroleum coke, oil, sewage, metallurgy, chemical, and other fields. Basic construction includes a body, disc, bellow, stem and pin. Most of them are made of CrNiMo, CrNi, or Cr. The disc moves along seat central line, making the changes of valve seat in direct proportion to disc stroke.
     
    Advantages of Cast Steel Globe Valve
    1. The surface of DIN flange cast steel bellows seal globe valve is polished twice, thus gloss and smooth.
    2. There is little friction between sealing faces.
    3. Precision casting body and CNC treated disc offer accurate and efficient regulation and throttling for pipelines.
    4. Different from ball valve, globe valve is very effective in regulating flow in a pipeline.
     
    Features of Cast Steel Globe Valve
    1. Compared with gate valve, DIN flange cast steel bellows seal globe valve has a simpler structure and needs fewer repairs.
    2. When bellows sealed globe valves are on and off, the stroke of disc is not long. As a result, globe valve height is lower than that of gate valve, but the structure is a bit longer.
    3. Now that there is no relative sliding between disc and valve sealing face, abrasion and scratch are not serious.
    4. The valve stem axis of DIN flange cast steel bellows seal globe valve is vertical to valve seat sealing face.
    5. When the nominal pressure of medium flow direction is below 16MPa, medium flows up from lower disc. When it exceeds 20MPa, medium flows down from upper disc, strengthening sealing performance. When in operation, flow direction is one way and is unchangeable.
    6. Medium passway is zigzag inside valve body. Therefore, the hydraulic resistance is large, consuming quite a bit energy.
