PR-9 Series
High Temperature Stainless Steel Pressure Regulator

The PR-9 Series high temperature pressure regulator
is designed for the pressure control of gases and
liquids up to 1000° F. All metal components in
and out of the flow stream provide the user with
extended reliability in rigorous high temperature
ambient and process applications. This regulator can
also be used in applications where no elastomer’s are allowed in the flow stream. The PR-9 is equipped with a metal-to-metal seat and will not provide bubble-tight shut-off . If shut-off is required, a high temperature shut-off valve must be placed upstream of this regulator.
