SMC Corporation NAR425-N04BG-R Pilot Regulator

SMC NAR425-N04BG-R is a pilot-operated regulator designed for precise downstream pressure control in pneumatic systems with 1/2" NPT ports. It employs an internal pilot-operated relieving design, enabling the regulator to bleed pilot air to maintain steady outlet pressure under changing flow. It covers a set-pressure range of 0.05 to 0.83 MPa (7 to 120 psi) and tolerates a maximum inlet pressure of 1.0 MPa, with a proof pressure of 1.5 MPa. Air consumption is 5 L/min (ANR) at maximum pressure, supporting predictable performance in automated lines. This compact regulator is suitable for close-to-use pressure regulation in automation and tooling applications where space is at a premium.
