Valve options
- Aug 23, 2018 -

The most common Valve types to be fitted with bellow seals are the gate and globe designs (see Figure 1).These are very suited for use with bellows due to their internal construction and axial movement of the Valve stem.
Based on available information, it seems that current bellow seal Valves range in size from 3 mm NB to 650 mm NB. Pressure ratings are available in from ANSI 150# to 2500#. Material options for the Valves include carbon steel, stainless steel and exotic alloys.
