Wilkerson Compressed Air Regulator Brass 125 Psi

Wilkerson RB3-C2-W000 Brass Water Pressure Regulator – 125 PSI Max, 1/4 in. NPT

The Wilkerson RB3-C2-W000 is a commercial-grade, high-performance water pressure regulator designed to protect downstream equipment by reducing high, fluctuating inlet pressures to a stable, user-defined operational level. Constructed from a heavy-duty, corrosion-resistant brass body, this robust regulator is engineered specifically for water and non-potable aqueous fluid lines. Featuring a balanced valve design, it minimizes the impact of upstream pressure variations to deliver constant, uniform output. Utilizing 1/4-inch NPT ports, this industrial regulator handles a maximum inlet pressure of 125 PSI and comes equipped with a convenient, non-rising adjustment knob with a built-in push-lock mechanism to prevent accidental setting drift.

Technical Performance and Design

• Heavy-Duty Brass Construction: The solid brass housing provides excellent mechanical strength, structural integrity under pressure, and superior resistance against water-borne mineralization and internal oxidation compared to standard aluminum regulators.

• Balanced Valve Mechanism: Engineered with an internal balanced poppet that neutralizes the variable forces exerted by fluctuating inlet supply lines, ensuring a steady, reliable downstream delivery pressure.

• Push-Lock Adjustment Knob: The non-rising adjustment knob allows for effortless, tool-free pressure tuning. Simply pull up to adjust the pressure setting, and press down to lock the knob securely into place against system vibration.

• Dual Gauge Ports: Incorporates dual 1/4-inch NPT gauge ports that can be utilized to install an analog pressure gauge for real-time tracking, or plugged to function as additional system outlet feeds.
