Advantages
1. It is suitable for the transportation of corrosive media and the regulation of interception and flow rate. According to the different materials, it can be used at temperatures ranging from - 14℃ to +140℃.
2. The over-current parts are assembled by RPP or PVDF injection moulding parts, which have excellent corrosion resistance.
3. The sealing diaphragm is made of F46 or PFA, and its folding resistance is more than 12000 times. Its corrosion resistance is similar to that of F4.
4. The screw lifting structure is adopted with large opening and closing moment and good stability.
