Dairies in the USA can now save up to 90% on CIP media, due to the special LEFF® (Low Emission Flip Flop) water-economizing function from GEA. GEA has been granted approval under the US Pasteurized Milk Ordinance (PMO) for this control function for double-seat valves. The valves from the 24/7 PMO 2.0 Valve® range are deployed in non-aseptic dairy processes where milk is drawn off, stored, distributed and filled.
Sealing zones on the valves can be cleaned separately by LEFF® with their sealing function entirely retained. This means that they can work around the clock, regardless of process run-times and product pressures, without interrupting production for CIP.
LEFF® is integrated as standard in the T.VIS A-15 control head of the 24/7 PMO 2.0 Valve®. Path-controlled electronics, for which GEA already holds a patent, pulse-controls the moment and degree of opening of the valve disk with absolute precision.
GEA engineers have now rearranged double-seat valves for milk processing in line with the PMO specifications, and eliminated the risk with a special underpressure in the leakage space suctioning up any cleaning medium that may have overflowed, thus pressure cannot build up on the valve disk.
