Função LEFF® - Flip-Flop de Baixa Emissão
LEFF® significa Low Emission Flip-Flop (Flip-Flop de Baixa Emissão). A função LEFF® está integrada no cabeçote de controle T.VIS® A-15 e pode ser facilmente ativada. O movimento intermitente do disco da válvula melhora claramente a eficiência da limpeza.
Resource-efficient solution
At GEA we are continually innovating to improve our customers’ efficiency, reduce their consumption of valuable resources and improve sustainability.
The LEFF® function integrated in GEA T.VIS A-15 control tops has been awarded the GEA Add Better label* for its positive impact on reduced water consumption. Conventionally, mixproof valves run a time-based seat lifting cycle to clean valve seats and intermediate cavity. The LEFF® function is the smarter, more efficient way. The valve opens in a pulsating mode, controlled by path-measuring instead of fixed intervals. This increases the intensity of flushing and effectively shortens flushing times for water and chemicals. It has been proven to saves up to 92% of water and cleaning agent used.
*The add Better label relates to the LEFF® function integrated in GEA T.VIS control top, released in 2003, which saves 92% of water in comparison to conventional valve seat cleaning.
How does the LEFF® function works?
Características
- Não é necessária programação complicada no CLP
- Não é necessária tecnologia adicional do sistema
- Independente do ciclo de tempo do CLP
- Monitoramento automático das funções de elevação
- Redução significativa dos custos (perdas médias em CIP, custos de esgotos, etc.)
For double-seat valves it simply utilizes standard feedback units, without needing any special components. The straightforward configuration using two push buttons on the T.VIS® cap allows the LEFF® function to be activated separately at any time during set-up for the valve or double disc or even both.
Modulation of the valve disc during lifting makes it possible to drastically reduce cleaning agent consumption, respectively discharge into the drains and thus, reducing operating costs, compared to the conventional seat cleaning method.
