PR-9
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 fl ow 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 elastomers are allowed in the flow stream.
The PR-9 is equipped with a metalto- metal seat and will not provide bubble-tight shutoff. If shutoff is required, a high temperature shutoff valve must be placed upstream of this regulator.
