Parker's P3RA302 is a high pressure pneumatic regulator expertly designed to provide a constant pressure output from a fluctuating supply
pressure, increasing efficiency and performance in applications that require high capacity and accurate process control. High precision
pneumatic regulators are designed to provide a constant pressure output from a fluctuating supply pressure, much the same way an
electronic pressure regulator works. Pressure regulators provide varying degrees of accuracy with regards to their reduced pressure output.
General purpose regulators work for most fluid power applications. However, for more pressure critical applications, precision regulators can
provide the control required.
When designing a pneumatic system it is important to determine not only the air flow that the application will require, but also the acceptable
level of pressure variation. Sometimes an existing pneumatic application does not meet the customer's needs with regards to pressure
control and/or stability. Variables, such as temperature changes, inlet pressure changes, variations in flow, excess downstream pressure,
cycling, etc., can cause issues with pressure stability. For these critical applications, precision regulators can provide the control required. An
internal poppet valve, which is balanced by utilizing a rolling diaphragm, insures a constant output pressure even during wide supply pressure
Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the air supply
in accordance with the flow velocity.
