End Connections Flanged (Typically ANSI Class 125 or 150 RF). The specific size (e.g., 1", 2") is defined by the full order code. Outlet Pressure Range Defined by the "/13" configuration. This is a factory-calibrated range. Example ranges for a similar code could be 20 to 60 psig (1.4 to 4.1 bar) or 50 to 150 psig (3.4 to 10.3 bar). The exact range must be confirmed from the original factory data sheet. Maximum Inlet Pressure Dependent on the body rating, but typically suitable for several hundred psig.
