HFS4A Cylinder Compact High-Flow Gas Regulator

Brand: Swagelok Company
Swagelok® HF series gas pressure regulators use a gas actuated pressure-sensing assembly to precisely control outlet pressure. 
 
A slight decrease or increase in the outlet pressure causes the pressure-sensing assembly to expand or contract, respectively. The expansion or contraction of the pressure-sensing assembly moves the poppet to provide precise pressure control.
Features
  • Compact, high-flow design
    • Less than half the size of conventional diaphragm pressure regulators
    • Flows up to 300 std L/min
  • Innovative gas-actuated pressure-sensing assembly
    • Low supply-pressure effect ensures precise pressure control
    • Low droop eliminates the need for adjustment in many systems
    • Outlet tolerates maximum rated inlet pressure without damage
  • Self-centering poppet
    • Minimizes outlet pressure creep
  • Tamper-free design
    • Reduces potential of improper adjustment
    • Simplifies installation
  • High-purity design
    • Tied poppet for clean operation and positive shutoff
    • All-welded design—no seals to atmosphere
    • 5 μin. Ra electropolished finish
    • 316L VIM-VAR stainless steel body
  • Choice of end connection/mounting styles
  • Model: Preset Cylinder
  • End Connections: 1/4" high-flow VCR gland
  • Preset Outlet Pressure
    • psig: 80
    • bar: 5.5
    • kPa 551.6
  • Supply Pressure Maximum
    • psig: 3,000
    • bar: 206
    • kPa: 20,680
  • Testing: Inboard helium leak tested to a rate of 1 X 10-9 std cm3/s
  • Process
    • Swagelok Ultrahigh-Purity Process Specification (SC-01)
    • Electropolished, Ra 5µin. (0.13 µm average)
  • Materials of Construction
    • Body: 316L Stainless Steel Vim Var
    • Diaphragm: Alloy 625
    • Stem: 316L Stainless Steel
    • Poppet: PCTFE or Polyimide
