Amflow® PR7B Back Pressure Regulator

 A&H Enterprises, Inc. was founded in 1989.  As an engineering company, A&H Enterprises has been involved in the development of more than thirty industrial products, specializing in the innovative design and development of flow control devices, ranging from actuators, back pressure regulators, filters, and flow control valves.

 

A&H Enterprises has patented Amflow® Technology which provides state-of-the-art flow control utilizing a simple mechanical design.  This technology is widely used in the oil industry and is well suited for automated control where precise control of very high pressure is required.

 

A&H Enterprises has also developed a wide variety of devices for use in fire and safety systems.  These products were developed by A&H Enterprises to meet specific requirements.

 

A&H Enterprises’ strategic decision-making process is fast, unrestricted, and in-house. The Directors’ policy of reinvesting profit into the company has resulted in great financial stability and flexibility.

 

In 2000, A&H Enterprises moved to new facilities to expand the operations which give easy access to both international seaports and airports, as well as increasing its service capabilities.

 

The PR7B Back Pressure Regulator represents the latest technological 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).
