Parker R45-02B Miniature Air Regulator 150 Psi 1/4 Npt

Product Description

The PARKER R45-02B is a miniature compressed air regulator designed to control downstream air pressure in pneumatic systems. Part of the Parker R45 series, it accepts supply pressures up to 150 psi and regulates output across a range of 0 to 60 psi. The 1/4 inch NPT port accommodates standard compressed air lines, and the unit supports a maximum airflow of 35 CFM. A built-in relief function vents excess pressure when the regulator is adjusted downward, making it suitable for precise pressure management in compact installations. The plastic body keeps weight low at 0.38 pounds. Licensed technicians and industrial maintenance professionals are the typical installers.

The R45-02B fits compact pneumatic control applications where space is limited and a full-size regulator is not practical. It is commonly installed on compressed air branch lines, point-of-use tool stations, small pneumatic actuators, and instrument air circuits. The miniature form factor suits panel-mount and inline installations where airflow demands stay within the 35 CFM rating. Minimum operating temperature is 40 degrees F, so indoor or climate-controlled environments are the appropriate setting for this regulator.

Key Features

• Miniature R45 series design for space-constrained pneumatic installations
• Regulates compressed air from 0 to 60 psi with supply up to 150 psi
• Maximum airflow capacity of 35 CFM
• 1/4 inch NPT end connections for standard compressed air plumbing
• Built-in relief function for safe downstream pressure adjustment
• Lightweight plastic body at 0.38 pounds

Compatibility

Designed as an OEM-style replacement or direct addition for compressed air systems requiring a miniature inline regulator with 1/4 inch NPT connections and a 0 to 60 psi output range.

Installation Notes

Installation should be performed by a qualified pneumatic technician or industrial maintenance professional familiar with compressed air systems. Depressurize and lock out the air supply line before installing or removing the regulator. Confirm that upstream supply pressure does not exceed 150 psi and that ambient temperatures remain at or above 40 degrees F during operation. Do not exceed the rated 35 CFM flow capacity, as oversizing the demand can cause unstable regulated pressure.
