Valve for gas cylinder

摘要

The valve has a longitudinal bore (10-1) opening at an upper end of a body (10), and a closure unit (14) and a rod (16) assembly to open and close the valve. The assembly is supported inside the bore by the body that directly surrounds the assembly to have a single interfacial annular interstice to be sealed for avoiding gas leak at the upper end. A fixed base is formed on a lower tube (12) separated from the body by a lower end.
