Cylinder valve VK-20 MIX with a nipple for a siphon tube No. 942.900.17
The valve with a siphon tube is a closing element of the cylinder during filling, storage and consumption of gas through it, intended for installation on cylinders of welding mixtures for effective mixing of gases and formation of a homogeneous mixture.
It is most often used to pass argon through liquid carbon dioxide in the process of filling the cylinder, during which carbon dioxide changes into a gaseous state, mixes well with argon and forms a homogeneous mixture. And also for mixing compressed gases of different densities and removing the liquid phase from the down of the cylinder.
