Alfa Laval describes a better way to clean double-seat mixproof valves and reduce water and CIP liquid consumption even further. This involves quick and repetitive opening and closing of the seat, rather than exposing valve surfaces to CIP liquid ow for a given duration of time. This discovery was made at one of Alfa Laval’s process facilities. Alfa Laval engineers observed that, during the first fractions of a second of a cleaning cycle, the ow of CIP liquid created a high level of shear stress on the valve surfaces used less water than traditional seat lift and seat push cleaning, and increased overall cleaning efficiency.
