Six-port, brass barstock, high flow manifold regulator for high purity inert gas applications

The 485 Series regulator provides primary source pressure control in high flow inert gas applications such as bulk gas distribution systems, high purity chamber pressurization, and liquefied hydrocarbon analysis. Internal pressure equalization mitigates the delivery pressure variation from changing flows that are typical in pipelines. The CONCOA 485 Series regulator is rear panel mountable using a bracket or may be connected directly to the gas source via a flexible hose.

  • Balanced stem seat design ensures constant delivery pressure at high flows
  • Cleanroom assembly eliminates contamination at installation
  • Rear panel mount easily vents exhaust gases
  • Spectometric helium leak check verifies leak integrity
  • Max inlet pressure (bare body): 3000 PSIG (210 BAR)
  • Body: Brass barstock
  • Bonnet: Chrome-plated, die-cast zinc
  • Gauges: 2 in (50 mm) diameter brass
  • Seat: PCTFE
  • Filter: 40-micron 316L stainless steel mesh
  • Temperature range: -40°F to 140°F (-40°C to 60°C)
  • Diaphragm: 316L stainless steel
  • Cv: 1.0
  • Helium leak integrity: 1 x 10⁻⁸ scc/sec
  • Internal seals: PTFE
  • Ports (bare body): 1/2 in FNPT (inlet and outlet); 1/4 in FNPT (gauges, relief valve, and auxiliary inlet)
  • Conformances: Cleanliness meets or exceeds CGA G-4.1; ANSI/ASME B40.1; PED 2014/68/EU; CRN OH5216
