American standard cast steel globe valve Product Overview

Flange Connection Steel American Standard cast steel globe valve for ANSI Class150 ~ 600. Operating temperature -29 ~ +425 ℃ (carbon steel), - 40 ~ +200 ℃ (stainless steel) on a variety of pipelines. Used to cut off or connect the medium in the pipeline, through the use of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing media and urea and other media.
 

The Structural Characteristics of American standard cast steel globe valve

 1, American standard cut-off valve product design and manufacturing in line with the US standard ASME B16.34 and other foreign advanced standards. 
 2, the valve body shape for the spherical or streamlined, handsome in appearance, the flow channel shape straight, fluid resistance is small. 
 3, closing valve closure (valve) and the valve seat sealing surface with a tapered seal, close the force is small, resistant to erosion, sealing and reliable. 
 4, the seat can be replaced valve seat, can be any combination with the closure of the sealing surface material matching to meet the requirements of various conditions to extend the service life.
