Bermad IR-130-3W-XZ Plastic Hydraulically Operated Pressure Sustaining Valve with 3-Way Control & Manual Selector
The Bermad Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting.
Disclaimer : Tee and Angle patterns contain the correct shape and brand but coils/plumbing will match accordingly to the PSV Pressure Sustaining Valves.
The pilot continuously senses the downstream valve pressure and controls the valve’s opening and closing rate accordingly, by increasing or decreasing the flow from the valve control chamber to downstream.
APPLICATIONS

INSTALLATION
- Ensure enough space around the valve assembly for future maintenance and adjustments.
- Prior to valve installation, flush the pipeline to insure flow of clean fluid through the valve.
- For future maintenance, install Isolation gate valves upstream and downstream from BERMAD control valve.
- Install the valve in the pipeline with the valve flow direction arrow in the actual flow direction.
- For best performance, it is recommended to install the valve horizontally and upright.
- After installation carefully inspect/correct any damaged accessories, piping, tubing, or fittings.
