Watts FluidAir R230-03D Pneumatic Pressure Regulator

Description:

The Watts FluidAir R230-03D Pneumatic Regulator is a 3/8 inch NPT air pressure regulator designed to provide precise and stable downstream pressure control in compressed air systems. Rated for a maximum inlet pressure of 250 PSI, it automatically reduces supply pressure to a controlled level, helping protect pneumatic equipment and ensure consistent system performance. The regulator is commonly installed in manufacturing facilities, automation systems, pneumatic control panels, packaging machinery, instrumentation equipment, and industrial compressed air networks.

Applications:

The Watts FluidAir R230-03D 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 compact, diaphragm-operated design provides reliable pressure regulation for downstream valves, cylinders, actuators, and other pneumatic devices, helping improve operational efficiency, reduce pressure fluctuations, and extend equipment service life.
