Norgren R07-100-RNKA Air Regulator 1/4 Npt 300 Psi

Product Description

The NORGREN R07-100-RNKA is a standard compressed air pressure regulator designed for inline pressure control in pneumatic systems. It accepts a maximum supply pressure of 300 psi and regulates output within a 5 to 125 psi range, making it suitable for a wide variety of compressed air applications. The regulator features a relieving function, which allows downstream pressure to vent when the set point is reduced. Port connections are 1/4 in NPT with a 1/8 in NPT gauge port. Weighing 0.35 pounds, this is a compact unit at 3.0 inches overall height. It is installed by pipefitters, HVAC technicians, and maintenance mechanics on compressed air distribution lines.

This regulator is used in industrial, commercial, and light-duty production environments where consistent downstream air pressure is required. Typical applications include pneumatic tool supply lines, process air circuits, and equipment requiring a stable regulated pressure below 125 psi. The relieving design allows pressure adjustments without isolating the downstream circuit, which simplifies on-the-fly tuning during commissioning or maintenance.

Key Features

• Maximum supply pressure of 300 psi for use on standard industrial compressed air systems
• Output pressure range of 5 to 125 psi covers most pneumatic tool and equipment requirements
• Relieving relief function vents excess downstream pressure when set point is lowered
• 1/4 in NPT inlet and outlet ports for direct inline installation on standard pipe or tubing fittings
• 1/8 in NPT gauge port for optional pressure gauge monitoring
• Compact 3.0 in overall height suits space-constrained panel or inline installations

Compatibility

Designed as an OEM-style replacement or direct-install regulator for compressed air systems using 1/4 in NPT porting and operating within a 300 psi maximum supply pressure envelope.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and isolate the compressed air supply line completely before installing or removing the regulator. Use thread sealant rated for compressed air service on all NPT connections and torque fittings according to fitting manufacturer guidelines. Verify downstream pressure with a calibrated gauge after setting the regulator to confirm the output is within the required range before returning the system to service.
