Type CNA
Product information
Lohse type CNA is a stainless steel knife edge gate valve and suitable for pulp and slurry media with a fairly high viscosity content of up to 4.5%. The valve is designed to prevent deposition and accumulation of solids.
All Lohse valves use the modular Lohse actuator system, where a choice can be made between manual actuators (handwheel, handwheel with rising spindle, T-wrench, chain) and non-manual actuators (electric and pneumatic).

Application
The Lohse knife edge valve type CNA can be used wherever the medium contains solids. The knife edge valve is designed to cut through the medium. This valve is used for pulp and paper applications, sewage and water treatment processes and applications where the medium contains fibers, potatoes, cement, gypsum, dust and other solids.
The CNA can be equipped with various drive systems and can be customized to specific conditions. The compact design features plastic inner shells that minimize internal spaces and minimize the torque required.
