Product Description
The BERMAD Adjustable Direct Acting Pressure Reducer is actuated by a pressure-responsive diaphragm, which seeks to reach an equilibrium between hydraulic and set spring force.
The BERMAD Model PRV is built of reinforced plastic that endows it with excellent hydraulic performance capabilities and high mechanical strength. It reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.

Technical Data
Operation
![PRV - 20mm - Operation](https://deeco-production.s3.amazonaws.com/images/PRV_-_20mm_-_Operation.width-1000.png)
The Upstream Pressure P1 applies balanced opening and closing hydraulic forces under Diaphragm 1 and above the Plug 2. The Downstream Pressure P2 applies hydraulic closing force under the plug, which seeks to reach equilibrium with the Set Spring 3 force. Should P2 rise above the setting, the hydraulic closing forces rise above the mechanical force of the spring, pushing the plug to modulate closed, and reducing P2 back to setting.
