P3RA302 is designed for applications that require high capacity and accurate process control in a small package.
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 variations.
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. A separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
Additional options available are internal check valve; non-relieving diaphragm, tapped exhaust, tamper resistant and screwdriver adjustment.
This series also carries certifications that make the units acceptable in zones 1 and 2 gas atmosphere, groups IIA and IIB and, 21 and 22 for dust atmosphere.
