Table 1. Outlet Pressure Ranges and Control Spring Data The 67C Series regulators are typically used to provide constantly controlled, reduced pressures to pneumatic and electro-pneumatic controllers and other instruments. These direct-operated regulators are suitable for most air or gas applications. Other applications include providing reduced pressures to air chucks, air jets, and spray guns. • Compact—The 67C Series regulators are engineered for outstanding performance in a compact, lightweight package. • Panel Mounting—Panel mount construction includes spring case with 1/4 NPTvent,...

Table 2. Available Constructions Table 3. Construction Materials Internal Relief (Types 67CR, 67CSR, 67CFR, If for some reason, outside of normal operating conditions, the downstream pressure exceeds the setpoint of the regulator, the force created by the downstream pressure will lift the diaphragm until the diaphragm is lifted off the relief seat. This allows flow through the token relief. The relief valve on the Type 67CR, 67CSR, 67CFR, or67CFSR is an elastomer plug that prevents leakage of air from the downstream to atmosphere during normal operation, thereby Smart Bleed Airset In some...

Figure 3. 670 Series Typical Panel Layouts CHANGEOVER VALVE FLANGE SCREW VENT POSITION Figure 4. 67C Series Vent and Drain Valve Positions DRAIN VALVE DRAIN VALVE DRAIN VALVE DRAIN VALVE DRAIN VALVE POSITIONS To determine the equivalent capacities for other gases, multiply the table capacity by the following appropriate conversion factor: 1.29 for 0.6 specific gravity natural gas, 0.810 for propane, 0.707 for butane, or 1.018 for nitrogen. For gases of other specific gravities, divide the table capacities by the square root of the appropriate specific gravity. To find wide-open flow...

Table 4. 67C Series Flow Capacities Three basic panels are available within the product line, each having one 67C Series pressure regulator connected to one or two gauges and a changeover valve. A single gauge typically shows loading pressure to the control valve. For more information, see Bulletin 62.3:670. NACE Universal Compliance Optional materials are available for applications handling sour gases. These constructions comply with the recommendations of NACE International sour service standards. The manufacturing processes and materials used by Emerson assure that all products specified...
