Youfumi lined diaphragm valve is ideally suited for shut-off, flow control and throttling of corrosive process media in either liquid or gaseous state.Its main features are heavy-duty, robust construction, maintenance-free, easy replacement of components on site. Convenient, flexible and accurate open or close.2. It can sustain any corrosive medium in addition to the? ? Molten alkali metals and fluorine elements? ? . It is ideal products used in chlor-alkali, industrial in organic chemicals, metal and mining, nitrogen and phosphatic fertilizers, petroleum refining, pharmaceutical etc.3. It is not applicable for diaphragm used in medium with hard particles, which will cause diaphragm damage and leakage.4. The working temperature cannot exceed the specified range.5. Open the diaphragm too frequent will influence the sealing performance.6. Lining material: PFA, FEP, GXPO etc.7. Operation methods: Manual, worm gear, electric, pneumatic and hydraulic actuator.8. Youfumi lined diaphragm valves are available as per the needs of applications in additional sizes and other than standard materials.Material Specification:1. Lock screw: A320 B82.
