- a compressed gas can be in particular nitrogen or butane.
- Other means of pressurization can be envisaged, in particular a piston.
- a valve consists of a valve body, having a inlet passage and an outlet passage, closure means for, in response to an actuation command, switch the input passage communication with the outlet passage, and elastic return means to, in the absence of an actuation command, request the resources shutter in closed position.
- Such valves can be fitted with a additional gas outlet (PGA), in the form of an orifice in the valve body, and opening into the upper part of a container on which valve is mounted, which upper part contains gas used to pressurizing the liquid.
