Bulletin 71.1:CSB400 Pressure Registration and Downstream Control Line Connection Internal Registration CSB400 Series regulators with an “IT” or “IN” in the type number have internal pressure registration. Internal registration utilizes an internal sense tube located in the outlet of the body to communicate the outlet pressure to the actuator chamber. Internal registration is used for ease of installation.

Bulletin 71.1:CSB400 Capacity Information appropriate conversion factor: 0.775 for air, 0.628 for propane, 0.548 for butane or 0.789 for nitrogen. For gases of other specific gravities, multiply the given capacity by 0.775 and divide by the square root of the appropriate specific gravity. Tables 9 through 28 provide natural gas regulating capacities at selected inlet pressures and outlet pressure settings for the CSB400 Series, which includes configurations that include the Integral Monitor and Slam-shut.
