The VACOMASS® elliptic control valve is a technically optimized sliding gate control valve with gas-tight shut-off and an elliptical control aperture. It is used for precise and low-loss control of air flow and distribution in the aeration tanks of a wastewater treatment plant.
Within the usual control range the valve has a stable control curve, and it can be used from 0-100% stroke. It is designed to have a pressure loss of less than 10 mbar at full load and 100% stroke. The design stroke in control mode typically ranges between 30 – 70%, pressure drop will range between 8-15 mbar.
