Parker R230-02E Air Regulator 1/4 in Npt 250 Psi

Product Description

The PARKER R230-02E is a diaphragm-operated compressed air regulator designed to control downstream pressure in pneumatic systems. Built from aluminum, it accepts a 1/4-inch NPT port connection and handles supply pressures up to 250 psi. The diaphragm design provides stable, responsive pressure regulation across a wide range of flow conditions, with a maximum air flow rating of 80 CFM. An integrated relief function vents excess pressure when the regulated pressure rises above the setpoint, protecting downstream components. The R230-02E is suited for light industrial, workshop, and trade-service pneumatic applications where consistent regulated output is required.

This regulator is appropriate for compressed air systems in residential and light commercial service environments. Typical installations include pneumatic tool supply lines, air-operated control systems, and equipment requiring steady regulated air pressure at the point of use. The 1/4-inch NPT port size makes it compatible with standard small-bore pneumatic fittings and piping commonly found in trade service setups. A 1/4-inch gauge port thread is present for optional pressure gauge installation, though no gauge is included with this unit. The unit is rated for operation down to -40 degrees F, making it suitable for cold-climate installations.

Compatibility

Designed as an OEM-style replacement or new-installation regulator for compressed air systems using 1/4-inch NPT connections and requiring supply pressures up to 250 psi. Part of the Parker R230 series.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic systems and applicable codes. Depressurize and isolate the air supply line completely before removing or installing the regulator. Use thread sealant rated for compressed air service on all NPT connections and avoid over-tightening fittings into the aluminum body. Verify regulated output pressure with a calibrated gauge after installation before returning the system to service.
