Safe Product Selection:
The complete catalog contents must be reviewed to ensure that the system designer and user make a safe product selection. When selecting products, the total system design must be considered to ensure safe, trouble-free performance. Function, material compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system designer and user.
Caution:
Do not mix or interchange valve components with those of other manufacturers.

Pressure-Reducing Dome-Loaded

Swagelok® Pressure-Reducing, Dome-Loaded Regulators

pressure-reducing-dome-loaded-regulatorsPressure-reducing dome-loaded regulators deliver many options and features that include compact sizes, dome- and air-loaded styles, piston sensing, balanced designs, high-purity, high-flow, integral pilot-operated, and differential. They can be ordered as both venting and non-venting. Multiple gauge connection configurations are also available.

High-Purity, High-Flow Gas Regulators (HF Series)

high-purity-high-flow-gas-pressure-reducing-dome-loaded-regulatorsSwagelok® 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 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 imporper 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 connecion/mounting styles
    • 1/4 in. VCR® split-nut connections
    • 1/4 in. and 3/8 in. butt weld connections
    • IGC™ II surface mount
