Long Service Life With Reduced Maintenance

The locally designed and manufactured Rotating Disc Valves feature a unique rotating/shearing disc which provides a self-lapping rotation and enhanced seat cleaning action which cuts through solids giving a long-lasting tight shut-off.

The metal-to-metal seating makes the valves abrasion resistant over a wide temperature range. Their high pressure capability, which is better than industry standards, allows the force to be distributed over a larger area resulting in reduced trim wear.


The openness of the valve body provides space for the product to be freely displaced by the lever arm and disc with each cycle. Fines cannot compact in small open areas and possibly jam components as is the case with other valve concepts.

Each time the valve opens to discharge the product, a vortex is caused by the eccentric body to port configuration. The settled media swirls, thereby cleaning the valve’s interior.
