  • Page 9: Intended Use

    Intended use Intended use Gas pressure regulators consisting of an HON 512 actuator assembly combined with an HON 650 pilot can be used to maintain the outlet pressure constant within set limits within a gas regulating line regardless of gas discharge changes and inlet pressure changes. These gas pressure regulators work on a purely pneumatic basis.

  • Page 10: Device Models

    Description Device models Gas pressure Gas pressure regulators consisting of an HON 512 regulator unit combined with an HON 650 pilot are available in a number of versions. These versions are derived from the various regulator versions possible combinations between the various pilot and actuator assembly versions.
