Watts R119-03B Regulator
The Watts R119-03B is a high-capacity pneumatic pressure regulator designed for demanding industrial and HVAC applications requiring precise compressed air control. Built with a robust die-cast aluminum body and a corrosion-resistant finish, this unit manages a maximum inlet pressure of 300 PSI while providing a regulated output range of 0 to 60 PSI. The 3/8-inch NPT ports allow for high flow rates with minimal pressure drop, making it an essential component for maintaining consistent downstream pressure in multi-stage pneumatic systems. The R119-03B regulator features a balanced valve design to ensure stable regulation despite fluctuations in primary line pressure. Its large technical diaphragm and non-rising adjustment knob with a standard lock ring enable technicians to achieve granular set-point accuracy, which is critical for protecting sensitive pneumatic actuators and air-powered machinery from over-pressurization.
Product Specifications and Performance Features:- Port Size: 3/8" NPT female connecting ports for streamlined installation.
- Pressure Rating: Handles up to 300 PSI primary inlet pressure.
- Regulation Range: Delivers precise 0-60 PSI reduced pressure output.
- Flow Capacity: Optimized internal porting for high SCFM requirements.
- Construction: Heavy-duty zinc die-cast housing for long-term durability in mechanical rooms.
- Self-Relieving Design: Allows for venting of excess downstream pressure for system safety.
How do I install the Watts R119-03B in a high-flow system?
Ensure the flow direction aligns with the arrow on the body. For optimal performance, install the high-pressure air regulator as close as possible to the point of use and use a filter upstream to prevent debris from fouling the valve seat.
Can this regulator handle fluctuating inlet pressures?
Yes, the balanced valve construction compensates for upstream pressure spikes, keeping the 3/8 NPT regulator output consistent within its specified spring range.
Is the R119-03B suitable for water service?
No, this specific model is engineered for compressed air and neutral gases. For fluid applications, compatibility with the internal diaphragm and seal materials must be verified against specific Watts fluid-service models.
