Watts R119-08CG-M2 Pneumatic Pressure Regulator

Description:

The Watts FluidAir R119-08CG M2 Pressure Regulator is a 1 inch NPT relieving pneumatic pressure regulator designed to provide accurate and stable downstream pressure control in compressed air systems. With an adjustable outlet pressure range of 0–125 PSI and a maximum inlet pressure of 300 PSI, it automatically reduces supply pressure to protect downstream equipment and ensure consistent system performance. It is commonly installed in manufacturing facilities, automation systems, pneumatic control panels, process equipment, and industrial compressed air networks requiring high-flow pressure regulation.

Applications:

The Watts FluidAir R119-08CG M2 is widely used in compressed air distribution systems, industrial automation equipment, assembly lines, process control systems, material handling equipment, air-operated tools, OEM machinery, and manufacturing plants. Its diaphragm-operated, relieving design and heavy-duty tee handle provide fast response and precise pressure regulation, helping improve reliability, reduce pressure fluctuations, and extend the service life of downstream valves, cylinders, actuators, and other pneumatic components. It is particularly suited for high-flow applications where consistent regulated air pressure is essential.
