Hello,
about safety valve devices,
what is better for venting a atmospheric storage tank contains liquid phase of volatile material ?
Is the Conventional safety valve (PSV) or pilot operated safety valve?

3omar,
In general, pilot operated is better...!

Well.
what does it make pilot operated type is better than the conventional ?
-Can tolerate maximum operating pressure close to valve set pressure
-Lower blowdown
-Lower required overpressure to be full open
-Faster response and better sensing

If you have an atmospheric tank, then putting a pressure operated vent on, venting to atmosphere seems counter to your equipment.
What is the safe working pressure of the vessel?

Mr paul,

Then the psv makes sense. I agree with the other comments from Fallah but want to add the following:

Apart from the above discussion, you can consider the flame arrester with the venting device, if there is any flammable materials in the tank.
