Product Overview
The WILKERSON R03-02-Q00 is a precision pneumatic pressure regulator engineered for accurate downstream pressure control in compressed air and inert gas systems. As a member of the WILKERSON R03 series, this regulator utilizes a balanced poppet and diaphragm sensing mechanism to maintain a stable outlet pressure regardless of fluctuations in inlet pressure or flow demand. The unit features a 1/4″ port size (02 designation) and is factory-configured with a non-relieving adjustment (Q00 suffix), making it ideal for applications where venting of excess downstream pressure is not required or desired. Its robust construction and sensitive response make it a reliable choice for industrial pneumatic circuits requiring consistent pressure regulation.

Engineering Features & Advantages
- Precision Pressure Control: Balanced poppet design ensures accurate and repeatable outlet pressure regulation, minimizing droop and variation across changing flow demands.
- Non-Relieving Configuration: The Q00 non-relieving design prevents downstream air from venting to atmosphere, conserving compressed air and suitable for dead-end or closed-loop applications.
- Industrial Reliability: Built for continuous operation in demanding pneumatic environments, with durable diaphragm and seal materials resistant to typical industrial contaminants.
- Direct Fit Replacement: Exact dimensional and functional compatibility with WILKERSON R03 series regulators and OEM equivalents, ensuring drop-in installation without modification.
- Compact Inline Design: Space-efficient body allows easy integration into existing pneumatic panels and manifold assemblies.
Typical Industrial Applications
This WILKERSON R03-02-Q00 regulator is commonly deployed in compressed air systems for plastic injection molding machines, packaging and labeling equipment, CNC machine tool air circuits, and general factory automation pneumatic control panels. It is also suitable for instrumentation air supply, blow-off stations, and any industrial process requiring stable, non-relieving downstream pressure regulation.
