Home > Products > Semiconductors > NCV (PTFE) For Pharmaceutical, Biotechnology, High Purity Chemicals and Semiconductor Process Equipments NCV check valve efficiently allows low-pressure operation in forward direction while blocking flow in reverse direction The NCV check valve body is made up of Polytetrafluoroethylene and springs Polychorotrifluoroethylene. This allows safe and reliable use in applications with strongly acidic and alkaline chemicals. Design also allows usage for a wide range of chemicals Various packing materials Fluorine rubber, Ethylene propylene rubber, Prfluor, etc. are available to suit various application requirements in chemicals, pure water, air, gas etc. Superior corrosion resistance.
