Product Description
Cylinder valve refers to the valve installed on the cylinder to control the gas cut and flow.Also called "bottle valve".Cylinder valves of different structures are generally used for cylinders with different media.Their common characteristics are mostly manual, simple structure, small size, high strength, operating temperature of -40~60℃, material can adapt to the physical and chemical characteristics of the medium and commonly used copper.
CGA valve is the American standard valve series, very versatile, Oxygen, Argon, CO2, Hydrogen, Helium and other kinds of gas valves, for medical, industrial, welding and other industries.
