High-Flow, Manual Gas Regulators
The Swagelok® HF series high-flow, manual gas regulator features a load spring which interacts with a unique pressure-sensing assembly to precisely control outlet pressure. Outlet pressure is adjusted by turning the handle. Inline and modular surface-mount (MSM) models are available
