In the petroleum, chemical, pharmaceutical, fertilizer, power industry and other fields, chlorine gas is often used as an oxidant in chemical reactions due to its superior oxidation properties, and it is also rejected because of its highly toxic properties. Then, on the valve for chlorine, the user should choose what kind of product to ensure that the safe transportation of chlorine and liquid chlorine does not leak.

Then, on the valve for chlorine, the user should choose what kind of product to ensure that the safe transportation of chlorine and liquid chlorine does not leak.
Due to the superior sealing performance of the bellows shut-off valve when it is connected to or cut off the pipeline medium, it is often used in the transportation process of chlorine, liquid chlorine and other toxic media to ensure its zero leakage. Chlorine/chlorine corrugated pipe stop valve is suitable for nominal pressure: PN1.6～4.0Mpa/150LB～600LB, working temperature -46~425°C petroleum, chemical, pharmaceutical, fertilizer, power industry, etc. Chlorine/chlorine/phosgene On the line of the /chlorosilane service, cut or switch on the line medium.
The special corrugated pipe seal valve for liquid chlorine valves adopts a unique bellows seal design, which completely eliminates the problem of valve stem seal leakage and meets the most stringent leakage level requirements. 1 The bellows in the body cavity is completely isolated, and the packing in the 2 stuffing box is an accessory. The zero leakage characteristic of the VTB imported corrugated pipe stop valve improves the safety of the equipment, saves a lot of energy, reduces maintenance costs, and provides a clean and safe working environment for industrial applications. Ordinary bellows stop valve bellows in the valve body cavity, the medium in the pipe directly impacts the bellows, the bellows is easy to be damaged and leaks, and the sealing effect is not achieved. The improved valve bellows is lifted into the valve cover, and the bellows is protected. It effectively avoids the scouring of the medium and the destruction of the bellows by impurities in the medium. Connection standards include flange, butt weld and socket weld, pressure grade up to PN40, ANSI300 and CLASS600. Chlorine/chlorine liquid body material is selected from low temperature corrosion resistant steel (LCB/LF2), nickel plated with titanium stainless steel Tube or Hastelloy C276, disc LF2+PTFE/STL
The imported bellows shut-off valve can also be used in the chlorine medium process of chlor-alkali, polysilicon, PVC, propylene oxide, titanium tetrachloride, and various high-risk medium fluids in the industry.
