Stainless steel construction delivers superior corrosion resistance and long life in aggressive atmospheres, reducing replacement costs and unplanned downtime. The 316 stainless body, stainless adjusting knob, and stainless bonnet translate to dependable performance in marine, food-processing, and dental environments, extending service intervals and lowering total cost of ownership. The 1/4" PTF port with a 1/8" gauge port and T-bar adjustment with snap-action lock provides accurate set-points and stable operation, minimizing set-point drift in fluctuating air networks. A maximum inlet pressure of 20 bar and an outlet range of 0.3–8.5 bar address typical factory air demands while enabling precise pressure tailoring for sensitive actuators and valves. Relieving design ensures safe venting during regulation, improving operator safety and system reliability. The compact footprint (86 mm height, 38 × 42 mm) and panel-mount facility simplify installation in tight enclosures, reducing panel cutouts and wiring effort. With 7 dm3/s flow capability (15 scfm) and FPM elastomers, the unit handles high-demand cycles without material permeation. The combination of high corrosion resistance, robust materials, and compact integration makes it well-suited for demanding industrial automation and sanitary/compliant lines.

FAQs
The R05-232-RNLA is designed for panel mounting and fits compact spaces thanks to its 86 mm height and 38 × 42 mm footprint. It features a 1/4" PTF port and a 1/8" gauge port to support inline sensing. When installing, ensure a flush panel cutout, proper gasket seating, and secure mounting screws to minimize vibration. The reliving valve reduces heat load and vibration during venting, improving reliability in confined panels.
Key specs include a maximum inlet pressure of 20 bar and a regulated outlet range of 0.3 to 8.5 bar (4 to 123 psi). The regulator is suited for compressed air at -25 to 80 °C (-13 to 176 °F) and provides a flow of about 7 dm3/s (15 scfm). With T-bar adjustment and a snap-action lock, you get stable set-points even under fluctuating supply pressure, which minimizes downstream actuator stiction and cycling.
Yes, the unit’s 316 stainless steel body and stainless steel adjusting knob deliver excellent corrosion resistance, aligning with harsh-environment expectations typical in marine and petrochemical facilities. While exact certifications aren’t listed, the material selection and NACE-friendly construction support use in corrosive atmospheres, where durable regulators help maintain process stability and reduce maintenance frequency.
Certification data such as SIL, CE, or IP is not explicitly listed in the provided data. However, the regulator uses FPM elastomers and a stainless-steel construction suitable for demanding applications. For medical or food-processing lines, verify your facility’s specific regulatory requirements and potential compatibility with FPM elastomers, hygiene standards, and cleaning routines before deployment.
Maintenance benefits come from corrosion resistance, robust stainless-steel components, and a relieving design that reduces overpressure incidents. The compact footprint simplifies service access, while the reliable T-bar adjustment minimizes drift-related re-tuning. These factors contribute to lower downtime, fewer part replacements, and a favorable total cost of ownership in automated plants with frequent cycling and demanding environments.
