CSB400 Series regulators are typically installed on industrial and commercial applications. See Table 1
for Available Configurations. Low, Medium and High outlet pressure constructions are available via Types CSB400, CSB420 and CSB450, respectively, that provide outlet setpoints ranging from 17 mbar to 3.0 bar / 7 in. w.c. to 43.5 psig. Also available are upstream monitoring configurations such as Types CSB410 and CSB430, which are installed upstream of the primary regulator to provide overpressure protection.
Types that include an “F” refer to the cold temperature construction of the base Type number. For example, the Type CSB404F provides a cold temperature construction of the Type CSB404. Refer to the Operating Temperature section found on the following page for additional information regarding temperature capabilities and refer to Table 7 for inlet pressure limitations. For types that include an “F”, refer to the base type number for general information such as Principles of Operation, Maintenance instructions, Warnings and Cautionary notes.
