Watts 112-2RL Model M Air Pressure Regulator

The Watts 112-2RL Model M Air Pressure Regulator provides precise downstream pressure control from 0 to 125 PSI in pneumatic and compressed air systems. This diaphragm-operated regulator features a compact aluminum body with 1/4 in. NPT connections and a manual adjustment knob for fine-tuning, delivering high flow and high sensitivity suitable for industrial automation and instrumentation panels. Capable of withstanding supply pressures up to 300 PSI, it is commonly installed in air compressor systems, pneumatic control panels, manufacturing equipment, process automation, packaging machinery, instrumentation systems, and industrial air distribution networks. By maintaining consistent operating pressure, it helps reduce downstream fluctuations, protect pneumatic components, and improve equipment performance and service life in commercial and industrial environments. Common replacements include Watts R374-02C, Watts R374-02CG (with gauge), and Parker Watts 06R Series regulators. Model M is designed for inline air system mounting and is ideal for OEM machinery, machine builders, and system integrators requiring reliable regulation for air-operated tools and process control.
