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

HF series regulators provide precise pressure control in high-purity, high-flow applications. Their compact, high-flow design allows for close spacing of system components and process lines.

Swagelok HF series manual gas pressure regulators feature a load spring which interacts with a unique pressure-sensing assembly to precisely control outlet pressure. Outlet pressure is easily adjusted even in tight spaces by turning the narrow-profile handle, available with a finger-tight grip and knurled diameter for positive actuation. While compact in size, HF series regulators can handle flow rates up to 200 std L/min, allowing design efficiency when building systems. A self-centering poppet minimizes creep and is offered in PCTFE for leak-tight shutoff.

HF series regulators’ innovative, pressure-sensing assembly design with a welded diaphragm results in low droop, which eliminates the need for adjustment in many systems. A high-purity design features a tied poppet for positive shutoff and metal-to-metal seal to atmosphere and a 316L VIM-VAR stainless steel body internally electropolished and finished to 5 μin. (0.13 μm) Ra.

HF series regulators also feature:

  • Ability to handle maximum inlet pressures up to 500 psig (34.4 bar)
  • Manually adjustable outlet pressure up to 150 psig (10.3 bar)
  • 316L VIM-VAR stainless steel body for ultrahigh-purity applications
  • 1/4 in. VCR® metal face seal; 1/4 in. tube butt weld; 1.5 in. and 1.125 in. modular surface-mount end connections
