Low Temperature and Cryogenic Ball Valves

 

Low temperature and cryogenic service ball valves

These 3-piece, full port ball valves are specifically designed to operate reliably to temperatures as low as -450ºF. 

 

Applications for PURITY valves are typically for liquefied gasses such as oxygen, nitrogen, hydrogen, fluorine, helium and methane.  Special manufacturing (cleaning) procedures are used to ensure degreasing before final assembly and testing.

 

Offered in sizes up to 14" and for pressures as high as 1,500 PSI, they are constructed entirely of 316L SS and can have any of the following connections types:

 

 

You might notice the elongated bonnet design which reduces heat exchange between the process fluid and environment, positioning the gland packing closer to the ambient temperature zone and thereby protecting it from freezing.
