Single Stage, High Pressure Regulator - APR66 Series

Brand: Parker Hannifin

The APR66 Series is a high pressure reducing, single-stage regulator designed to operate at inlet pressures up to 6000 psig as well as very high outlet pressures up to  6,000 psig.

The APR66 offers a full range of pressure sensing without time consuming spring and piston change outs.  It utilizes a low friction adjusting screw, which provides a smooth operation of the regulator.

It is available with a self-relieving option. The unique thrust bearing allows the operator to easily turn the adjusting knob with full pressure applied.
Features
  • Piston sensing
  • Thrust bearing allows low actuating torque and precise setability
  • Cleaned for O2 service is standard
  • Low friction adjusting screw sleeve provides smooth operation
  • Optional self-relieving feature allows user to decrease outlet pressure in closed systems. Feature is actuated by turning the adjusting knob counterclockwise
