American Standard Cast Steel Globe Valves product overview

Flange   connection steel American standard globe valve for ANSI Class150 ~   600. Operating temperature -29 ~ + 425 ℃ (carbon steel), - 40 ~ +200 ℃   (stainless steel) of the various pipelines. It is used to cut off or   connect the medium in the pipeline. It can be applied to a variety of   media such as water, steam, oil, nitric acid, acetic acid, strong   oxidizing medium and urea through the selection of different materials.
 

American Standard Cast Steel Globe Valves structure characteristics

 1,   American Standard Cast Steel Globe Valves product design and   manufacture in line with the US standard ASME B16.34 and other foreign   advanced standards. 
 2, the valve body shape spherical or streamlined, handsome in   appearance, the shape of the runner through-type, fluid resistance. 
 3, the closure of the closure valve (valve) and the valve seat sealing   surface with a tapered seal, the closing force is small,   erosion-resistant, reliable seal. 
 4, the valve seat for the replacement of the valve seat, can be any   combination of material with the closure of the sealing surface   matching, to meet the requirements of a variety of conditions, to extend   the service life.
