Almost all VACOMASS® control valves were developed and optimized especially for aeration air for the use in activated sludge tanks, grit chamber and exhaust air treatment. All of them close bubble-tight and can be combined customized with different makes and types of actuator and fulfill requirements of the advisory leaflet DWA-M 229.
The VACOMASS® jet control valve is an innovative, flow-optimized stainless steel control valve that closes gas-tight and offers a linear operating characteristic over virtually the entire operating range. The valve has been developed and optimized specifically for high precision air control and distribution with minimal pressure loss, resulting in comparatively low operating costs.
The VACOMASS® elliptic diaphragm 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. The valve has a falling flow axis to achieve sensitive control of normal and tangential flows (e.g. after elbows), and is designed according to DIN EN 60534-2-3.
