Watts R364-02C Regulator

The Watts R364-02C Regulator is a miniature pneumatic pressure regulator designed for precise downstream control in industrial air service applications. Built with a rugged brass body and Buna-N diaphragm, this 1/4 inch NPT regulator handles a 300 PSIG maximum inlet pressure while maintaining a highly sensitive 0-125 PSI output range. As a relieving type regulator, it automatically vents excess downstream pressure, making it ideal for dead-end applications where pressure creep must be avoided. This unit is technically identical to part number 0622614, ensuring a direct drop-in replacement for existing Parker-Watts R643-Series configurations. The non-rising adjusting knob allows for easy setpoint calibration in tight spaces, and the 10 SCFM flow capacity supports consistent air delivery for control circuits and pneumatic instrumentation. This compressed air regulator includes dual 1/8 inch NPT gauge ports for flexible monitoring and a diaphragm-operated design for rapid response to demand changes.

• Durable Brass Construction: Provides superior corrosion resistance and longevity compared to standard plastic miniature units.
• Precise Pressure Management: Maintains a stable 0-125 PSI setpoint even during fluctuating supply pressures up to 300 PSIG.
• Automatic Pressure Relief: The relieving diaphragm prevents over-pressurization of downstream components by exhausting excess air.
• Compact Footprint: Designed for industrial air preparation in confined enclosures or individual tool stations.
• Simplified Integration: Fully compatible with systems requiring 0622614 or R364-02C specifications.

Is the Watts R364-02C compatible with fluids other than air?
This 1/4" NPT air regulator is specifically engineered for compressed air service. While some non-relieving brass variants may be used for water, this relieving type regulator is strictly for air to ensure proper venting of the diaphragm.

Does this regulator come with a pressure gauge?
The R364-02C features two 1/8" NPT gauge ports for installation flexibility but does not include the gauge itself. This allows technicians to select a gauge face that matches their specific system requirements.

How do I handle maintenance on the R643-series?
The diaphragm-operated assembly and Buna-N seals are high-wear components. For optimal performance in FRL systems, ensure the incoming air is filtered to prevent debris from fouling the poppet seat.
