What kind of valve is this?

[tree Of Meraki]

I need a one way check valve where the valve only opens if a pressure of about 10 bar is reached, does anyone know what kind of valve this is, and where i can buy it

You may find exactly what you want or may have to get a solenoid operated valve and a pressure operated switch. It may be cheaper.
