Parker R210-02A Air Regulator 1/4 in Npt 150 Psi 14 Cfm

Product Description

The PARKER R210-02A is a diaphragm-operated compressed air regulator designed to control downstream pressure in pneumatic systems. Built from zinc construction, this regulator handles supply pressures up to 150 psi and maintains a maximum working pressure of 145 psi. It delivers up to 14 CFM of airflow through a 1/4 inches NPT port. The R210-02A includes a relief function, allowing excess downstream pressure to vent when the set point is exceeded. It is installed by licensed pipefitters, industrial mechanics, and HVAC-R technicians working on pneumatic control circuits, compressed air distribution lines, and equipment requiring regulated supply pressure.

The R210-02A suits residential and light commercial applications where a compact, reliable inline regulator is needed to step down compressed air supply pressure. Its 1/4 inches NPT end connections are compatible with standard pneumatic fittings and tubing used in air tool supply, instrument air, and control system applications. The adjustable pressure range of 2 to 40 psi makes it well-suited for downstream equipment requiring lower regulated pressures from higher-pressure supply lines. No pressure gauge is included, though a 1/4 inches gauge port is available for field installation of a separate gauge.

Key Features

• Diaphragm-operated design provides stable downstream pressure regulation
• Built-in relief function vents excess downstream pressure automatically
• Maximum supply pressure of 150 psi with working pressure rated to 145 psi
• Adjustable output pressure range of 2 to 40 psi
• 14 CFM maximum airflow capacity through 1/4 inches NPT connections
• Zinc body construction suited for compressed air service

Compatibility

Designed as an OEM-style inline regulator for compressed air systems using 1/4 inches NPT connections and requiring a regulated output pressure within the 2 to 40 psi range.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with pneumatic systems and compressed air distribution. Depressurize the supply line fully before installing or removing the regulator. Follow applicable codes and the equipment manufacturer guidelines for thread sealant use on NPT fittings. Inspect the downstream circuit before pressurizing to confirm all connections are secure.
