Watts R10-04B Regulator

For mid-range pneumatic system control, the Watts R10-04B general purpose regulator provides the consistent downstream pressure needed for sensitive air tools and HVACR actuators. Engineered with a balanced poppet design, this 1/2" NPT port regulator significantly reduces the effects of inlet pressure fluctuations, ensuring your set point remains stable even as tank pressures cycle. The diaphragm operated mechanism delivers quick response times, which is critical for maintaining performance in high-flow applications up to 100 SCFM.

The Watts R10-04B features a rugged zinc body and a rolling diaphragm for extended service life in demanding mechanical rooms. With a maximum inlet rating of 300 psi and an adjustable output range of 0-60 psi, it is the ideal choice for low-pressure secondary loops. The non-rising adjustment knob is designed for tamper resistance and allows for easy panel mounting via a standard 2-inch diameter hole. Two 1/4" NPT gauge ports are included, which can also serve as additional full-flow outlets depending on your manifold configuration.

• Precise Pressure Regulation: Features a balanced poppet to counteract inlet pressure variations.
• High Flow Performance: Supports up to 100 SCFM, making it suitable for larger pneumatic circuits.
• Durable Construction: Built with a zinc body and Buna-N seals for reliable fluid power control.
• Space-Efficient Design: The compact footprint and panel mount capability allow for installation in tight enclosures.

What is the difference between the R10-04B and the R10-04C?

The "B" suffix denotes the 0-60 psi secondary pressure range, while the "C" model is typically rated for a 0-125 psi range. Always match the spring range to your specific application for better resolution.

Can the gauge ports be used as supply outlets?

Yes, the two 1/4" NPT ports provide regulated air and can be used to feed secondary gauges or small-diameter auxiliary lines without impacting the primary 1/2" flow path.

Is this regulator relieving or non-relieving?

This model is a relieving type, meaning it will exhaust excess downstream pressure automatically when the set point is lowered, which is the standard requirement for most air tool and control applications.
