VACOMASS® control valves
Control valves for aeration air
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.
VACOMASS® jet control valve
Unique control valve - best in performance
The VACOMASS® jet control valve is an innovative, flow-optimized stainless steel control valve. In terms of control range and product quality, this development represents a milestone in the evolution of air control valves and fittings. It is unique and with worldwide patent applications. It fulfills all requirements defines in the Advisory Leaflet DWA-M 229-1 (September 2017) and the new "Handbook of Energy North Rhine-Westphalia" (January 2018).
VACOMASS® elliptic diaphragm control valve
Control valve with lenticular shaped orifice
The VACOMASS® elliptic diaphragm control valve is a technically optimized control valve, especially developed for aeration air, closing gas-tight with a lenticular control aperture. Low pressure drop in the whole control range and high flow rate capacity for flexing and cleaning the diffuser with very low pressure drop are two of the main features (design according to DIN EN 60534-2-3).
VACOMASS® square diaphragm control valve
Control valve with square shaped orifice
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 (design according to DIN EN 60534-2-3).
