Ashcroft 500 Diaphragm Seal
Ashcroft® series 500 and 501 large diaphragm seals are small enough to be used in compact spaces, but provide sufficient displacement to drive a wide variety of instrumentation. Their all-welded construction prevents possible process media leakage where fugitive emissions are a concern. They are commonly used for corrosive processes, processes with elevated temperatures, viscous process media, limited space, water treatment facilities, and where male connections are preferred.
