Imported pneumatic fluorine lined control valve
Imported pneumatic fluorine lined control valve product overview
  YLOK imported pneumatic film fluorine-lined single-seat control valve. The inner wall and inner components of the valve in contact with fluid adopt high-pressure injection molding process, and are lined with corrosion-resistant and aging-resistant polyfluoroethylene propylene (F46). It is sealed with PTFE bellows. It is widely used for the control of strong corrosive media such as acids and alkalis and toxic and volatile gases and liquids.
Features of imported pneumatic fluorine-lined film regulating valve
1. Corrosion resistance: Almost able to withstand the corrosion of all media (including concentrated nitric acid and aqua regia).
2. Good sealing performance: double sealing with bellows and packing to ensure no external leakage.
3. Small leakage: Because the valve core and valve seat adopt soft sealing, the leakage is low.
4. Equipped with HA actuator, with large output force and compact structure.
