AMFLOW® PR7B Back Pressure Regulator

 

OVERVIEW 

The PR7B Back Pressure Regulator represents the latest technology advance in chemical injection pressure regulation.

Like Amflow® Flow Control Valves, the PR7B Back Pressure Regulators' operating torque requirements are very low throughout the operating range, thus making it suitable for automated chemical injection system applications. It may be configured with any Amflow® Electronic Valve Actuator. The PR7B is rated for pressure ranges from 7-bar (100 PSI) up to 414-bar (6,000 PSI).
