Intended use Intended use HON 5020 gas pressure regulators featuring an HON 640a / HON 642a pilot can be used to maintain the outlet or inlet pressure of a gas constant within a regulating line regardless of the influence of disturbance variables such as pressure changes and/or discharge changes. In addition, these gas pressure regulators can be used to implement an active-monitor regulator configuration.
Description Device models Gas pressure regulator Gas pressure regulators consisting of an HON 5020 regulator unit combined with a pilot from versions the HON 640a or HON 642a series are available in a number of versions. These versions are derived from the various possible combinations between the various pilot and actuator assembly versions.
Small labels must be used to color-code and explicitly name the gas pressure regulator’s lines connection lines (measuring impulse lines and operating lines) based on what the lines are intended for and their minimum nominal size. HON 5020 gas pressure regulator with HON 640a / HON 642a pilot...
