Watts R11-04C Regulator

The Watts R11-04C is a professional-grade 1/2 inch NPT pressure regulator designed for high-demand industrial air preparation and fluid control applications. As a veteran-preferred choice for HVACR pneumatic systems, this unit features a heavy-duty zinc body and a diaphragm-operated design that ensures tight pressure tracking and rapid response to downstream flow variations. Operating within a 0-125 psi output range, it provides consistent delivery even when faced with fluctuating header pressures up to a 300 PSIG maximum inlet rating. The standard relieving type mechanism allows for safe venting of excess downstream pressure when the setpoint is adjusted downward, protecting sensitive system components and instrumentation.

Built for the rigors of the mechanical room, the R11-04C integrates a T-handle adjustment for precise calibration and an aluminum spring cage for enhanced durability in corrosive environments. With a 100 SCFM flow capacity, it is engineered to minimize pressure drop while maintaining a stable secondary pressure setpoint. Whether you are managing compressed air lines or specialized liquid flow in commercial refrigeration, this Watts air regulator offers the reliability required for 24/7 industrial service. This model includes two 1/8-inch NPT gauge ports and is compatible with the GC230 pressure gauge for real-time monitoring of system performance.

Key Benefits:

• Precision Pressure Management: Utilizing a secondary aspiration feature, the Watts R11-04C delivers fast response times and maintains a steady 0-125 PSI range.
• Industrial Durability: The robust construction, featuring a zinc body and brass bottom plug, stands up to the mechanical stress found in high-flow HVACR installations.
• Simplified Field Service: The T-handle design allows for quick, tool-free adjustments by contractors in the field.
• Component Protection: Integral relieving type functionality prevents downstream over-pressurization during system fluctuations.

Common Questions:

What is the maximum temperature rating for this regulator?
The Watts R11-04C is rated for operation between 40°F and 120°F (4.4°C to 48.9°C), making it suitable for standard indoor mechanical and pneumatic applications.

Does this unit come with a pressure gauge?
This specific part number is the regulator only; it features two 1/8-inch NPT gauge ports for secondary monitoring, but the GC230 gauge or equivalent must be purchased separately.

Can this regulator handle media other than air?
While optimized as an industrial air preparation tool, the diaphragm-operated design is often utilized in water and fluid control systems; however, you should always verify chemical compatibility with the Buna-N seals for non-air media.
