A valve unit with a level indicator for containers, in particular containers for liquefied gases, comprising; a valve body having external dimensions and an external geometry compatible with filling equipment used for similar valve bodies, without a level indicator, and having a substantially axial gas duct, a piston shutter which may be axially displaced in the valve body to and from a valve seat in order selectively to intercept the gas duct, a control rod of a floating actuator extending into the gas duct and into an axial cavity of the piston, a primary magnet which may be displaced axially in the axial cavity of the piston under the action of the control rod in response to a variation of the level in the container, a level indicator including a moving assembly subject to the magnetic field of the primary magnet in order to display the gas level detected by the floating actuator, the level indicator comprises a housing for the moving assembly which is secured to the valve body independently from the piston shutter. |
