Wilkerson R19-04-FA00B Air Regulator 1/2 Npt 300 Psi

Product Description

The WILKERSON R19-04-FA00B is a compressed air regulator designed to maintain consistent downstream pressure in pneumatic systems. Built around an aluminum die cast body, this Series 19 regulator handles supply pressures up to 300 psi and delivers a maximum flow rate of 64 CFM through a 1/2 inch NPT port. It includes a built-in relief function, which vents excess downstream pressure when the set point is exceeded. A 1/4 inch gauge port is provided for optional pressure monitoring. The modular connection design allows it to integrate directly into Wilkerson Series 19 filter-regulator-lubricator assemblies. Pneumatic technicians and industrial maintenance professionals install this unit as a standalone or modular line regulator.

This regulator is suited for compressed air service in industrial and commercial pneumatic systems where stable downstream pressure is required. The Common-P1 regulator type is designed for general-purpose pressure regulation in modular FRL (filter-regulator-lubricator) configurations. Typical applications include tool supply lines, automation equipment, and process air systems operating within the 0 to 125 psi output range. The unit is rated for operation down to -13 degrees F, supporting use in cold environments or unheated equipment rooms.

Key Features

Compatibility

Designed for use with Wilkerson Series 19 modular FRL systems using 1/2 inch NPT connections. Compatible with compressed air service only.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician. Depressurize and lock out the compressed air supply before installing or servicing this regulator. Ensure all NPT threaded connections are properly sealed with thread sealant rated for compressed air service. Do not exceed the rated maximum supply pressure of 300 psi at the inlet.
