Lohse type CNA

Product information

Lohse type CNA is a stainless steel knife gate valve suitable for pulp and slurry-shaped media with a fairly high solid particle content of up to 4.5%.  The valve plate is designed in such a way that the settling and accumulation of solids are prevented.  

All Lohse valves use the Lohse modular actuator system with a choice between manual actuation (handwheel, handwheel with rising stem, T-spanner, chain) and non-manual actuation (electric and pneumatic).

The CNA can be equipped with various actuator systems and be adapted to specific circumstances.  The compact design features plastic slide cups that minimise internal spaces and the required tightening torque.
