Check Valve

NCV Series (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

Made-to-order products

 
 

 Features

 
 

>>

 

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, Perfluoro elastomer, Kalretz and etc. are available to suit various application requirements in chemicals, pure water, air, gas etc.

 
 
 

>>

 

Variety of end configrations such as R, Rc and Flowell 20 & 60 series are available.
