Description
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
