Watts R119-03CG Regulator
The Watts R119-03CG is a high-capacity pneumatic pressure regulator designed for rigorous industrial and HVACR service applications requiring precise air pressure management. This 3/8-inch NPT compressed air regulator features a balanced valve design that ensures superior flow characteristics and high sensitivity, even during fluctuating supply pressures. Rated for a maximum inlet pressure of 300 PSI, the R119-03CG provides a reliable reduced output range of 2 to 125 PSI, making it a versatile component for tool lubrication systems and pneumatic control circuits. The relieving type regulator construction allows for the automatic venting of excess downstream pressure, which is critical for maintaining system calibration and safety. This specific configuration includes an integrated pressure gauge for immediate visual monitoring of the regulated line. Built with a durable die-cast aluminum body and an oil-resistant diaphragm, this industrial air pressure valve is engineered for longevity in high-cycle environments where consistent CFM performance is non-negotiable.
Key Benefits- Precise Pressure Control: Balanced valve construction minimizes the effect of inlet pressure variations on the downstream setpoint.
- Enhanced Safety: Internal relieving feature vents downstream overpressure for better system protection during adjustments.
- Durable Construction: Heavy-duty die-cast aluminum body and reinforced diaphragm provide reliable service in demanding mechanical rooms.
- Monitoring Ready: Factory-installed 0-160 PSI gauge allows for rapid setup and real-time troubleshooting of pneumatic lines.
- High Flow Capacity: Optimized internal porting ensures minimal pressure drop during high-demand cycles.
What is the maximum flow rate for the Watts R119-03CG?
Depending on the supply pressure, this unit typically handles flow rates up to 80-90 CFM, ensuring adequate volume for mid-sized pneumatic tools and actuators.
Can this regulator be used with moisture-heavy air lines?
While the internal components are corrosion-resistant, it is standard practice to install a filter-separator upstream of the R119-03CG to prevent contaminant buildup in the seat area.
Is the R119-03CG suitable for water service?
No, this model is specifically engineered for compressed air systems. Using it with water or hydraulic fluids will lead to premature seal failure and potential system damage.
