FC-55 Weight = 4.0 oz. These precision machined valves are designed and manufactured to provide Micro-Fine™ control of gasses and liquids. They haveamicrometer pitch (40 threads per inch) adjusting thread and precision machined tapered needle and seat. They are available as needle valves and flow control valves. The precision is shown on the chart below. You can see how close the actual flow (plotted dots) approaches a straight line. Also note that it takes 9 full turns to go from bubble tight shut-off to its full flow of 100 Standard Cubic Feet per Hour (1.67 SCFM) at 80 psi inlet. Features • Linear control to 100 SCFH @ 80 psi (see chart below). • Micrometer pitch adjusting thread, 40 TPI, .025 per turn. • 10-32 or 1/8 NPT ports. • Stainless steel needle - 3° taper. • Friction O-Ring provides “stay-put” adjustment. • Knurled adjusting knob with set screw lock. • White Delrin® knob. • Brass body. • Buna-N seals. • Operating temperature (0° to + 180°F). • 100% tested, “Bubble-tight” shut-off. • Air or Hydraulic service to 150 psi.
