One of our customers was experiencing severe blockages and instrumentation damage in their modulating knife gate control valves. These issues resulted in a loss of level control, negatively impacting copper concentrate recovery.

Drawing on our extensive experience in abrasive fluid handling, PESSA developed an innovative solution: the patented Floating Knife Gate Valve. This exclusive design eliminates the risk of jamming caused by solids accumulation and optimizes process control without requiring additional instrumentation in areas prone to slurry spills.

​

The results were remarkable:

✅ Improved operational efficiency, with precise level control.

​

✅ Complete elimination of blockages caused by solids accumulation, enhancing process continuity.

​

✅ Increased reliability, reducing maintenance costs and optimizing production.

​

Based on these benefits, our customer decided to standardize its plant transfer process using PESSA's VCSP (Knife Gate Valve for Pressurized Systems) technology, marking a significant improvement in operational efficiency.
