Description
The Watts R119-16J is a 2-inch pilot operated air regulator engineered for reliable, precise downstream pressure control in demanding compressed air and pneumatic systems. With a maximum inlet pressure rating of 300 PSI, this regulator is built to handle high-pressure supply lines while delivering stable, regulated output — making it an ideal choice for commercial and industrial HVAC, pneumatic controls, and air preparation applications.
Key Features
- 2″ pipe connection size for high-flow air regulation applications
- Pilot operated design for superior pressure stability and accuracy under varying flow conditions
- Maximum inlet pressure: 300 PSI (300#)
- Engineered for consistent downstream pressure control even at high inlet pressures
- Durable construction suited for commercial and industrial environments
- Designed for use in compressed air systems, pneumatic controls, and air preparation assemblies
Why Choose a Pilot Operated Regulator?
Unlike standard direct-acting regulators, pilot operated regulators use a pilot signal to control the main valve, resulting in tighter pressure regulation across a wide range of flow rates. This makes the Watts R119-16J particularly well-suited for systems where consistent downstream pressure is critical — even when demand fluctuates significantly.
Application
- Commercial and industrial HVAC pneumatic control systems
- Compressed air distribution and air preparation systems
- High-pressure inlet supply lines requiring precise regulation
- Pneumatic actuator supply circuits
