IR412-04-X32 High-Precision Pilot Operated Regulator

Brand: SOLH by Richge Technology (睿其格科技) 

Product Overview

     IR412-04-X32 belongs to IR series large-flow pilot-operated precision pressure stabilizer. This regulator is designed for heavy-demand pneumatic working conditions that require ultra-stable output pressure and tiny pressure fluctuation, fully dimension and performance interchangeable with SMC original IR412 series.

1. Core Technical Specifications

     --Net Weight: Approx. 1.0 kg

     --Mounting Options: Panel mounting or bracket mounting; pressure gauge installable on front or rear side

2. Nozzle-Flapper Pilot Operating Principle

     --Pressure Setting Stage: Rotate adjustment knob to compress internal spring and close the nozzle passage; pilot air pushes the main spool to adjust output pressure.

     --Stable Regulation Stage: Outlet pressure acts on the diaphragm to counterbalance spring tension, maintaining constant preset pressure.

     --Overpressure Relief Stage: When downstream pressure exceeds target value, diaphragm lifts to open the nozzle, pilot pressure drops instantly, and main valve releases redundant air at high speed. Core Advantage: Combined pilot control and relief structure delivers ultra-fast response speed, stable pressure output and outstanding large-flow performance.
