AMFLOW® PR7B-HP Back Pressure Regulator

 

OVERVIEW

The PR7B-HP Back Pressure Regulator has similar operating characteristics as the PR7B but is designed to operate at much higher pressures.  The PR7B-HP is rated for pressure ranges up to 827-bar (12,000 PSI).

Like Amflow® Flow Control Valves, the actuation force required to adjust the set point is very low, thus is suitable for automated chemical injection systems.  It may be configured with any Amflow® Electronic Valve Actuator.
