The recommended pressure limitations are stamped on the regulator nameplate Some type of overpressure protection is needed if the actual inlet pressure exceeds the maximum operating outlet pressure rating Overpressure protection should also be provided if the regulator inlet pressure is greater than the safe working pressure of the downstream equipment Ss EMERSON D100300XUS2 630 Series Specifications Available Configurations Type 630 Spring loaded reducing regulators Type 630R Spring loaded relief valves Body Size and End Connection Style 1 or 2 NPT Maximum Allowable Inlet Pressures Type 630 Regulators See Table 1 Type 630R Relief Valves See Table 3 Outlet Pressure Ranges 3 to 500 psig 0 21 to 34 5 bar with intermediate values shown in Table 2 Maximum Allowable Outlet Pressures See Table 2 Maximum Allowable Pressure Drops See Table 1 Temperature Capabilities Standard 20 to 150 F 29 to 66 C Optional 20 to 300 F 29 to 149 C Orifice Sizes 1 8 inch 3 2 mm 3 16 inch 4 8 mm 1 4 inch 6 4 mm 3 8 inch 9 5 mm or 1 2 inch 13 mm 1 The pressure temperature limits in this installation guide or any applicable standard limitati ion should not be exceeded Table 1 Maximum Allowable Inlet Pressures and Pressure Drops Maximum inlet pressure not to exceed 1500 psig 103 bar ORIFICE SIZE INCHES mm drops Some erosion of valve disks o
