Model 81 Multi Stage Precision Pressure Regulator

Part Number: M81

Rotork Fairchild Model 81 is a high flow two stage precision pressure regulator designed for applications that require high performance, low droop and accurate process control. The Model 81 combines a pilot control system with a basic force balance system to provide accurate output pressure regulation for both highly sensitive instrumentation and control circuits and in equipment requiring high flow with precise control. The Fairchild Model 81 features control sensitivity of less than 0.1" water column, very low consumption and high accuracy to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions. The Fairchild Model 81 pneumatic regulator will handle a 250 psi, 17 BAR maximum supply pressure and offers five (5)output pressure ranges from 0-20 psi, 0-1.5 BAR, 0-150 kPa up to 1-100 psi, 0.05-7 BAR, 7-700 kPa. The Model 81 precision regulator has a flow capacity of 50 SCFM, 136 m3/hr.
