8600 Series Mechanical Pressure Regulators

High precision, finer control.
Models 8601 / 8606 / 8607

The 8600 Series mechanical pressure regulators offer exceptional pressure output precision by virtue of their high-resolution control of the supply pressure. They are direct-acting, non-relieving units that provide bubble-tight shut-off on helium at 7 bar.
