These direct-operated regulators are suitable for most air or gas applications. Other appli- cations include providing reduced pressures to air chucks, air jets, and spray guns. Features • Compact—The 67CF Series regulators are engi- neered for outstanding performance in a compact, light-weight package. Internal Relief—The Type 67CFR has an internal relief valve with a soft seat for reliable shutoff with no discernible leakage. Panel Mounting—Panel mount construction includes spring case with 1/4-inch NPT vent, handwheel adjusting screw, and mounting nut. Instrument Supply Regulator—Provides a clean W7433 air supply to a variety of pneumatic and electro- pneumatic instrumentation. INLET PRESSURE OUTLET PRESSURE Digital Instrument Supply Regulator—Designed ATMOSPHERIC PRESSURE for the accuracy, repeatability, and hysteresis de- mands of digital instrumentation. Figure 2. 67CF Series Regulator Operational Schematic Pilot Supply Regulator—Improves the accuracy of two-path control regulators by reducing inlet sensi- tivity caused by fluctuating inlet pressures.Rugged Construction—The 67CF Series regula- tors are engineered for longer service life with minimal Pressure Loading Regulator—Provides high maintenance requirements. accuracy and improved performance in dirty steam service by eliminating the need for a pilot regulatorSecond Outlet—Body side outlet for pressure (see figure 2). gauge or other uses. Sour Gas Service Capability—NACE (MR0175)Powder Paint Coating—Fisher products are compliant construction available. powder paint coated, offering impact, abrasion, and corrosion resistance. Integral Filter—An integral filter ensures clean downstream air supply.Corrosion Resistant Fasteners—Adjusting screw and screws are double zinc-chromated for enhanced Ease of Maintenance—No special tools are corrosion resistance. required to perform maintenance, and all maintenance can be performed with the regulator in the line.
