Airgas Model 217B660 Stainless Steel Ultra-High Purity Single Stage Regulator With CGA-660 ConnectionTied diaphragm regulators resist attack from strong acid forming gases and facilitate safe handling of corrosive, toxic and reactive gases. They are especially useful in semiconductor manufacturing applications. Single stage design is recommended for use where inlet pressure does not vary greatly or where periodic manual readjustment of delivery pressure setting does not present a problem.

A needle valve is included on the outlet

These regulators also have a check valve cylinder connection that prevents contaminates from entering during cylinder changeover

thus not allowing any dropout regardless of differences in specific weight of the various compounds within the mixture

This minimizes cleanup time in vacuum purging and yields lower residual contaminant levels
