Hi, I was wondering what type of valve would be used to throttle steam in espresso machine steam wands?

The valve is required on the steam wand of an espresso machine. It is to open and close after being switched on and throttle steam coming from a boiler without reducing the pressure in the boiler significantly.

Most expresso machines use a needle valve to modulate the steam in the wands.
