DIN Standard Bellow Sealed Globe Valve 
DIN Standard Bellow Sealed Globe Valve Structural Features:
DIN Standard Bellow Sealed globe valve ( Os & Y Type ) is applied to various kinds of working conditions of pipelines such as petroleum, chemical industry, pharmacy, fertilizer, and power industry, etc, under nominal pressure in the PN1.6-40 MPa and operating temperature at -20 – 350℃, that is used to cut off or connected to the pipeline medium.
DIN Sandard Bellow Sealed Globe Valve Main Structural Features:
- This bellow sealed globe valve has logical structure, reliable seal, excellent performance and nice design.
- Sealing face of the lobe valve is overlayed by STL, which is friction-resistant, corrosion-resistant to ensure a long time use life.
- Stem Heat-Treatment and surface nitriding-treatment to sure function of corrosion-resistance and friction-resistance.
- The globe valve has double seal, thus the capability is more reliable.
- The stem of the globe valve may show the position of lift, thus it is more clearer.
- The parts material, flange and butt welding dimension may selected according to current operating condition or users’s requirement to meeting the requirements of various engineering.
