Precise and easy to maintain system
The fast, almost self-cleaning and remotely controllable butterfly valve with pneumatic actuator is based on the flow measurement integrated in the system and limits the flow to an arbitrarily adjustable quantity. As long as the maximum flow is not reached, the flap remains open, while the flow measurement system measures precisely even when partially filled. The system is installed wet in wastewater applications or fitted into a closed pipeline. Due to its easy disassembly and the maintenance opening, the partially filled pneumatic flow control is extremely easy to maintain.
Wet installation and dry installation
The system is available in two designs; firstly for wet installation, whereby the outflowing medium flows from the flap into the open shaft. Secondly for dry installation, where the throttle valve is located in a housing which is connected to the drain pipe of the building. In this case, the medium is guided through the building in a closed system.
Direct drive and scissors drive for closing the control flap up to 10m pre-pressure
The control flaps of the pneumatic discharge control are mechanically designed to close tightly in the standard version up to 4m (and as an option up to 10m) water column. This eliminates the need to install an additional knife gate valve. For the larger nominal diameters from 600mm upwards, the control valve is driven with a progressive transmission (scissor drive) so that the valve closes with even greater force.
