Amflow® PR7B-HP 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-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 setpoint is very low, thus is suitable for automated chemical injection systems. It may be configured with any Amflow®  Electronic Valve Actuator.
