piloted safety valve

[Fabius23]

Good morning to all I wanted to ask for an opinion on a project that I should carry out in my course of cad of the third year of mechanical engineering. It is a family of 4 piloted safety valves that process water with the following specifications: pressure 16 and 40 bar and flow 100 and 600 l/h. we have recommended a flow rate of 1 to 5 m/s, but to achieve this we must introduce very high load losses. not having any experience in this type of products my question is: is it normal to work with such data? and what are the usual construction solutions? Thank you in advance.

look at the competition products on the various catalogs and see in the splits as they are made. look at performance/loss curves and possibly contact some manufacturer looking for more detailed information.

2.5 m/s speed in the system are the rule.. .

I throw them: use large areas in the valve?

the project has been completed.. I attach a result layout. this table is just an old test but on this pc I do not have the final drawings.

@egy : you could not widen the surfaces not to exit the range indicated.

However thanks to those interested.
