CAUTION: Do not exceed maximum pres-
sure differentials for given valve sizes. The
maximum differential is the pressure the
valve has against it at shutoff. Too large a
differential can cause valve chatter and/or
prevent shutoff.

Steam Capabilities

Use a pressure drop of 50% of absolute inlet pressure (gauge pressure + 15 psi) for steam applications.
