Watts R119-02C Air Reg.

The Watts R119-02C Air Pressure Regulator is a heavy-duty, 1/4-inch NPT pneumatic control component engineered for high-demand industrial air preparation. Built with a rugged zinc body and a balanced poppet design, this 0-125 PSI air regulator ensures quick response times and accurate pressure regulation even during wide variations in flow. As a direct replacement for AL-483 and K-383 models, it integrates seamlessly into existing HVACR and pneumatic systems. It features a high-flow capacity of up to 100 SCFM at 100 PSIG inlet pressure and includes a secondary aspiration system to maintain set-point stability. The relieving type diaphragm and heavy-duty T-handle adjustment provide precise field calibration for technicians. Designed strictly for air service, this unit supports a maximum inlet pressure of 300 PSIG and operates within a temperature range of 40°F to 120°F. Whether used in high-flow industrial compressor systems or compact pneumatic loops, the Watts R119-02C delivers the reliability required for professional-grade air service.

• High Flow Performance: Delivers up to 100 SCFM, making it suitable for installations requiring constant pressure despite fluctuating air demand.
• Rugged Construction: Features a zinc body, brass bottom plug, and aluminum spring cage for long-term durability in harsh environments.
• Precision Control: The diaphragm-operated design with a balanced poppet ensures rapid response to downstream pressure changes.
• Contractor Friendly: Equipped with a heavy-duty T-handle for manual adjustments and two 1/4-inch NPT gauge ports (gauge not included; uses GC230).
• Cross-Compatibility: Confirmed replacement for common industry parts AL-483 and K-383.

Can the Watts R119-02C be used for liquid media?
No, this regulator is strictly designed for air service. Using it with water or other fluids can compromise the internal diaphragm and poppet assembly.

What is the maximum inlet pressure allowed?
The unit is rated for a maximum primary inlet pressure of 300 PSIG. Operating beyond this limit poses a risk of product rupture and system failure.

Does this unit come with a pressure gauge?
No, the R119-02C is a "without gauge" model. It features two 1/4-inch NPT ports for installing a standard 2-inch dial face gauge, such as the Watts GC230.

How do I ensure the regulator responds quickly to flow changes?
This model utilizes secondary aspiration and a balanced poppet, which are specifically engineered to provide a fast response and maintain stability under varying flow conditions.
