the Bermad 720-series pressure reducing valve

While pressure reduction valves such as the Bermad 720 series are designed for the long haul, it’s important to know how best to provide ongoing maintenance and service.

Maintaining pressure reducing valves helps ensure the product performs at its very best within your pipeline. This article outlines our key suggestions to maintain consistent operation of a pressure reducing valve, as well as discuss solutions to common troubleshooting problems.

If you are experiencing operating issues with a pressure reducing valve, consider some of our methods below:

New installation adjustments

If the valve is brand new, it may require correct set up and preparation for operation. In this instance, it is critical to follow the operating recommendations as described in the following video presentation. By following this demonstration, you can ensure that the valve has removed all excess air and the components are correctly set up for automatic operation.

Current installations

In older installations it is critical that the components are correctly serviced and all in perfect working order. If valve components are not properly maintained, this can be a cause for valve malfunction. The following video presentation describes the suggested procedures to ensure all components are serviced and fit for operation.

Problems due to entrapped air in system

In many instances, the issue is not the operation of the pressure reducing valve, but entrapped air within the pipe network. It is therefore critical to ensure the air release valves within your system are operating correctly. This might mean reviewing their location and performance in the pipeline.


If your system utilises CSA Fox – RFP air valves to prevent entrapped air, then the following video describes how to service the valve to maintain performance.

If all the outlined procedures have been followed , and the valve fails to operate as designed, then it is time to discuss the issue with Bermad. For further information on the 720 series, visit the product page for resources, or contact the nearest Bermad sales office for support.
