I Ball valve for imported electric nitrogen Product Overview
VTON's Ball valve for imported electric nitrogen It refers to the switch or regulating ball valve used to control nitrogen. The valve body channel and the connecting pipe have the same diameter, and the medium can flow almost without loss. Electric flange ball valve is suitable for two position cutting off and adjusting. It is mainly divided into two categories: electric soft seal ball valve and electric hard seal ball valve. Electric soft seal ball valve is mainly applicable to media with temperature below 250 ℃. Electric hard seal ball valve is mainly applicable to media above 250 degrees.
Nitrogen, chemical formula: N2 Normally, it is a colorless and odorless gas, and nitrogen is generally less dense than air. Nitrogen in total atmosphere 78.08% (volume fraction) is the main component of air. Cool to -195.8 At ℃, it becomes a colorless liquid and is cooled to -209.8 At ℃, liquid nitrogen turns into snow like solid. The chemical property of nitrogen is not active, and it is difficult to react with other substances at room temperature, but it can change chemically with some substances under high temperature and high energy conditions to produce new substances useful to mankind.
