Swagelok® High-Purity, High-Flow Gas Regulators (HF Series)
HF series regulators deliver precise pressure control with easy adjustments, ideal for high-flow and clean process demands.
Get Help Selecting RegulatorsHF series regulators are designed for high-flow systems, allowing for compact arrangement of system components and process lines. The gas-actuated models are notably smaller than traditional diaphragm-operated pressure regulators, offering a design that prevents tampering and simplifies installation.
These regulators are engineered for environments demanding high levels of cleanliness. Offering durable and precise pressure control, the HF series includes an innovative pressure-sensing assembly that minimizes supply pressure effects and droop, often removing the need for system adjustments.
They feature tied poppets for clean operation and secure shutoff, while an all-welded design eliminates atmospheric seals. Self-centering PCTFE poppets help prevent creep and ensure a leak-tight seal.
HF series regulators also feature:
- Ability to handle maximum inlet pressures up to 3000 psig (206 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® split-nut; 1/4 and 3/8 in. tube butt weld; 1.5 in. and 1.125 in. modular surface-mount end connections
