These are the normal, direct acting, heavy, 12V, solenoid valves:
Why do you need such a specific valve ? If it is to replace a valve, what is the brand and type of that valve ?
150 psi = 10 bar, that is a lot, and with an opening of 6-8mm, you need a strong valve.
Is that a design of an existing valve ? Or just a drawing ? Because I doubt if such a valve exists. The coil is too far from the core, so it won't work with such high pressures.
