Watts R374-02C Regulator

The Watts R374-02C Mini-Pressure Regulator is a robust 1/4 inch NPT industrial air preparation component designed for precise pneumatic pressure regulation. Built with a lightweight yet durable aluminum body, this 0-125 PSI regulator provides reliable performance in compact installations. It features a diaphragm-operated relieving design that ensures a fast response to downstream pressure changes, making it ideal for high-sensitivity applications. The unbalanced poppet is a standard inclusion, optimized for a maximum inlet pressure of 300 PSIG and a 10 SCFM flow capacity. This 4-way aluminum regulator includes two 1/8 inch NPT ports for easy pressure gauge integration. The non-rising, snap-lock adjusting knob allows for consistent set-point maintenance without the risk of accidental drift. Whether managing air-line demand or integrated into HVACR pneumatic controls, this Parker-Watts series miniature regulator delivers the technical accuracy required by professional contractors for stable system operation in temperature environments ranging from 40°F to 120°F.

• Precise Pressure Control: Diaphragm design offers rapid response and high sensitivity for critical pneumatic circuits.
• Compact Aluminum Construction: Lightweight 1/4" NPT frame saves space without sacrificing durability in industrial environments.
• Versatile Porting: 4-port configuration includes two dedicated 1/8" NPT gauge ports for versatile mounting and monitoring.
• Reliable High-Flow Performance: Supports up to 10 SCFM, ensuring adequate air supply for miniature pneumatic tools and actuators.
• User-Friendly Adjustment: Non-rising knob provides stable, repeatable settings for consistent system pressure.

Is the Watts R374-02C suitable for water service?
While the standard relieving model is optimized for air, non-relieving versions are typically required for liquid or water service to prevent constant bleeding.

What is the maximum inlet pressure for this miniature regulator?
This unit is engineered to handle a maximum supply pressure of up to 300 PSIG (20.4 bar).

Does this regulator include a pressure gauge?
No, this specific model (R374-02C) is the regulator only; however, it features two 1/8" NPT ports to accommodate standard gauges.
