1. Suitable for transportation and interception of corrosive media. The flow rate is adjusted according to the different materials. The operating temperature is -14℃ ~ 100℃. -40℃~140℃.
2. The flow parts are assembled from RPP or PVDF injection molded parts, with excellent corrosion resistance, easy operation, light weight, and can replace stainless steel valves.
3. The diaphragm of the seal is made of F46 or PFA, the number of folding resistance is ≥1200 times, and the corrosion resistance is equivalent to F4.
4. It adopts screw lifting structure, large opening and closing torque, and good stability.
