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
