Type 630 Regulator Introduction The Type 630 Big Joe™ regulators are directoperated, spring-loaded, pressure reducing regulators. They are available in 1 and 2-inch / DN 25 and 50 body sizes, and they are designed for maximum inlet pressures to 1500 psig / 103 bar and outlet pressures from 3 to 500 psig / 0.21 to 34.5 bar. The Type 630 can be used with natural gas, air, or a variety of other gases for such applications as first-stage farm-tap regulators or high-pressure industrial regulators. The Type 630 can be converted in the field to a relief valve or is available as the Type 630R relief valve/backpressure regulator; refer to the separate Type 630R Bulletin (71.4:630R) for information. Features • High-Pressure Capabilities—Inlet pressures up to 1500 psig / 103 bar and control pressures up to 500 psig / 34.5 bar. • Rugged Construction—Compact, sturdy design and solid metal construction provide a strong, reliable, long-lasting regulator. • Better Low-Pressure Control—The Type 630 is available in both high-pressure and low-pressure constructions; the low-pressure units have a larger diaphragm area to provide more accurate control of low-pressure settings. Figure 1. Type 630 Big Joe High-Pressure Regulator The manufacturing processes and materials used by Fisher® Controls assure that all products specified for sour gas service comply with the chemical and physical requirements of NACE International MR0175. • Sour Gas Service Capability—Optional materials are available for applications handling sour gases. These constructions comply with the recommendations of the NACE International MR0175.

SPRING CASE DIAPHRAGM CONNECTOR DIAPHRAGM ADAPTOR VALVE DISK AND HOLDER INLET PRESSURE OUTLET PRESSURE ATMOSPHERIC PRESSURE INLET ADAPTOR Figure 3. Type 630 Operational Schematic FULL SECTION PITOT TUBE [1-INCH / DN 25 SIZE ONLY] REGISTRATION HOLE [2-INCH / DN 50 SIZE ONLY] Principle of Operations Refer to Figure 2. In the regulator construction, outlet pressure registers beneath the diaphragm. As long as the outlet pressure is less than the set pressure, spring force on the diaphragm causes the lever to hold the valve open. When the outlet pressure exceeds the set pressure, the diaphragm...

Maximum Inlet Pressure and Pressure Drops MAXIMUM ALLOWABLE PRESSURE DROPS MAXIMUM ALLOWABLE INLET PRESSURE(1) ORIFICE SIZES Nylon (PA) and Polytetrafluoroethylene (PTFE) Disk psig Nitrile (NBR) Disk psig 1. Inlet pressure must not exceed the sum of the actual outlet pressure setting and the maximum allowable pressure drop. For example, with an outlet pressure setting of 200 psig / 13.8 bar and a 3/8-inch / 9.5 mm orifice with a maximum allowable pressure drop of 500 psid / 34.5 bar d, the maximum inlet pressure is 700 psig / 48.3 bar. 2.
