Product Overview
The VACOMASS® square diaphragm control valve is a technically optimized sliding gate control valve with a falling flow axis and gas-tight shut-off using a square shaped control aperture. It is used for precise and low-loss control of airflow and distribution in the aeration tanks of a wastewater treatment plant.
The control valve body consists of two halves that are designed to be of wafer or end-of-line type. The inner surface has a groove for a PTFE/ carbon gasket that makes the valve gas-tight and serves as an external guide for the valve´s knife-edge sliding gate. The combination of stainless steel on Teflon/carbon allows precision movement of the plate without vibrations or jamming.
