Valve selection help request

[coverall]

Hello.

I need a valve which will control the firewater pressure for the hyperbaric chamber fires. The valve will always provide the water pressure 5 bar over chamber pressure. Max. chamber pressure will be 7,5 bar.

For example if the chamber is at atmospheric pressure the fire water will come with 5 bar. Or if the chamber is 4 bar at that moment valve will set the water to 9 bar.

I'm waiting for your advises.

Thanks in advance.

Hi Coverall
The valve should be designed for the bigger dP in this case 7.5 bar.
You need look for pressure and temperature to avoid problems.
