The pulp and paper industry deals with highly abrasive, viscous, and sometimes corrosive fluids during its manufacturing processes. Whether it's handling black liquor, pulp slurries, or chemical additives, valves used in these operations must provide robust performance without clogging or leakage. In such applications, non lubricated plug valves prove to be an excellent choice due to their smooth operation, minimal maintenance, and high sealing integrity.
Industry Challenges
In pulp and paper plants, the challenges include:
-
High solid content in the flow
-
Corrosive bleaching chemicals
-
Scaling and buildup in valve internals
-
Continuous 24/7 operation demanding minimal downtime
Why Non Lubricated Plug Valves Fit the Bill
-
Full port design: Allows easy passage of fibrous or slurry-based fluids without clogging.
-
Non-stick PTFE sleeve: Resists pulp adhesion and prevents scaling.
-
Quarter-turn operation: Enables quick shut-off or flow regulation.
-
Low maintenance: Critical in minimizing production disruptions.
-
Resistant to harsh chemicals: Ideal for areas handling chlorine dioxide, peroxide, and caustic soda.
