PN25 SS Ball Valve , Flange Type Liquid Nitrogen Ball Valve

1 . The structure of reducing pressure holes in the valve core is adopted.
 

2 . The stem height is the optimal length obtained through calculation and testing.
 

3 . The gasket is made of ceramic filling material with stable sealing properties.
 

4 . In order to reduce the heat loss of the valve body, especially to ensure the use of the valve at ultra-low temperature, the valve body is specially designed to be light in weight and small in size.
 

5 . The long-shaft valve has a valve through which low-temperature fluid flows. The long stem is used to avoid the effect of external heat to keep the gland at normal temperature to prevent the performance of the cap seal from decreasing.
